Official version of WTC collapse theory fabricated by stealth Jewish Bush Administration is believed by nobody in Japan except by those Zionist Jew's ethnic Korean comrades at Soka Gakkai and Unification Church, therefore, we do not have to start our discussion from that official lies. Airplane fuel never can demolish WTC. And that there is no reason for WTC7 to collapse itself. Not necessary to argue on this point as we are not morons like the majority of rooters of Republican Party who still do not even know G. W. Bush's Jewish ancestry. 
Nothing but Small Tactical Pure Hydrogen Bomb can demolish the whole WTC buildings, pulverize the concrete into fine particles, create a molten steel pools at WTC basements and cause the earthquake of Magnitude 2.1. However, almost all would not instantly agree with this H.bomb theory. Therefore, thorough explanation will be given to those as follows:-
A SMALL HYDROGEN BOMB EXPLODED AT WTC BASEMENT :
A small tactical pure hydrogen bomb placed at the basement of WTC and WTC7 could have been exploded upward, then, steel structures absorb the extremely high heat and instantly evaporated or get melted. Thus, WTC start loosing the steel supports from bottom to top gradually while the explosion is moving upward. (See the left drawing by rense com. )

When the hydrogen bomb's blast reaches to the stories where airplane crashed, it was expelled out from the cracks of the building. The upper block of WTC looses steel support and come down perpendicularly.
PHREATIC EXPLOSION TO PULVERIZE CONCRETE INTO 70-300 MICRON PARTICLES :
The extremely high heat created by Hydrogen bomb caused phreatic explosion of water content of concretes used at WTC resulting to the huge blast of pulverized 70 - 300 micron particles. 
MOLTEN STEEL POOLS EXIST AT WTC BASEMENT EVEN MONTHS AFTER 9-11 :
The molten steels naturally fall down by gravitation and puddle at the basement of WTC. And such molten steel pool was found even months after 9-11. Peter Tully, president of Tully Construction as well as Mark Loizeaux, president of Controlled Demolition, Inc. who were contracted after 9-11 for removing the debris have admitted the existence of "literally molten steel".  Melting point of steel is 1585 deg. C, therefore, it would remain in liquid form for months after being heated at 10,000,000 deg. C. by hydrogen bomb explosion. A photo taken 5-6 weeks after 9-11 clearly shows hot, molten steel being removed by a power shovel. The same molten steel pool was found at the basement of WTC7 according to Mark Loizeaux. Thus, we should consider WTC7 collapsed due to the same reason as WTC towers did. Did Osama bin Laden do it? Such a stale joke is not pleased by any while cleverer people agree that this was done by Osama's superiors at a covert Jewish syndicate. Am not I right, Dr. Lowenstein? 

LOOKS LIKE A CONTROLLED DEMOLITION BUT WITH DIFFERENT BOMB :
When the steel structure get melted starting from the bottom, then, toward the top of the building , the building looses support and would gradually "get shortened" or "get disappeared". How does it look like? A perfect example of hydrogen bomb style  demolition is available at WTC7. See the left GIF.
Some may consider the ordinary controlled demolition method could have been applied at WTC, however, it does not explain existence of molten steel pools at the basements and pulverization of the concrete blocks into 70-300 micron. Moreover, it would be almost impossible to secretly plant plenty of explosives inside WTC without being known by third parties. However, it is understood such iron bombs could have been also used to destroy certain structure of WTC in order to make sure its collapse.

ANY OTHER TYPE OF NUCLEAR BOMB USED?
One may consider ordinary nuclear bomb might have been used to demolish WTC, however, one would realize it would be hard to conceal the use of nuclear bomb as far as there is any residual radioactive.
Conventional Plutonium bomb like one used in Nagasaki will discharge huge amount of Plutonium at explosion. What we call mini-nuke would use much less Plutonium and Uranium, however, it still creates the same residual of radioactive, too. Neutron bomb will discharge much Neutron and results in loss of many lives in the wide area. Conventional Hydrogen bomb is ignited by the explosion of atomic bomb which still contaminate the surroundings with radioactive. Therefore use of such nuclear bomb will be immediately known to the public. Thus, all of these does not fit WTC's case and phenomenon. Only when SMALL TACTICAL PURE HYDROGEN BOMB is used, there would be no residual radioactive, thus, sometimes hard to detect its use. This bomb is therefore, called "CLEAN NUCLEAR BOMB". 
WHY PURE HYDROGEN BOMB?
Conventional hydrogen bomb would discharge radioactive at explosion while pure hydrogen bomb is ignited with alternative heating media such as laser beam, magnetic field or plasma. Since no atomic bomb is used to ignite, no radioactive will be produced. However, nuclear radiation itself is emitted at the ignition, thus, may still cause human hazard due to the emission of alpha, beta, gamma ray as well as Neutron ray. But, such emission would be quickly diminished in a short period and may not be detected a few days after 9-11. This type of so called HOT FUSION is so far not confirmed of its fulfillment and existence as of today though many of the developed nation are making further research. And very huge facility would be needed to accomplish it. And such huge device cannot be placed in the basement of WTC without being known to the public. Then, how did you ignite the Hydrogen bomb, Dr. Lowenstein?

1600 BODIES VAPORIZED AT WTC
After 911, the corpse of victims had been searched at the site.  Dr. Charles Hirsch, the chief medical examiner, had tried to locate them as they should be at least found in parts. However, he could not trace any sign of 1600 victims. He told the family of the victims that many bodies – no one is sure how many – had been "vaporized" and were beyond identification. Yes, bodies were vaporized. If a hydrogen bomb is detonated at the basement of WTC, its extremely high heat will instantly vaporize the bodies and change them into heat and light. The thick, grey cloud of explosion at WTC could have contained those 1600 victims in the form of atmosphere.
RUBBLES CARRIED OUT BEFORE INVESTIGATION
After 911, wrecking companies immediately entered the sites and carried out the rubbles to Staten Island for 3 months. During such period, nobody else could have been allowed to enter the site to investigate the reason of the collapses. Dr. Lowenstein, did you arrange to erase the evidence of hydrogen bomb? Once hydrogen bomb is detonated, it will produce radiation isotope and decay product that would indicate the use of hydrogen bomb. Moreover, one who found the sign of molten or vaporized steel in rubbles, hew would recall the heat of hydrogen bomb. Therefore, you have quickly evacuated all the evidential rubbles. Otherwise, I should say you have arranged such destruction of evidence prior to the 911 in advance. Am I right?
THERMITE THEORY IS TO AVOID PEOPLE TO GAZE AROUND HYDROGEN BOMB THEORY?
Dr. Lowenstein, it seems you have employed Professor Jones of BYU, Uta to explain away the collapse of WTC in Thermite theory.  Your most concern is how to explain existence of the molten steel pools at the basements, right? It is true Thermite may produce enough high temperature to melt the steel and even sometimes evaporates the steel, therefore, Professor might have tried to impress people that this was the real reason for WTC's collapse. However, it will be necessary to bring huge amount of chemicals such as Iron Oxide and place them at many position of WTC. It is impossible to do so while many people are working in the building.
MAGNITUDE 2.1 EARTHQUAKE JUST BEFORE WTC COLLAPSE
Seismic wave of Magnitude 2.1 was recorded by Columbia University just prior to the collapse of both WTC towers. It was 20 times stronger than those earthquakes created by WTC collapse itself. It can be attributed to H. bomb, but not to Thermite. (This seismic wave was also recorded at the first WTC bombing in 1993. A typical phenomenon at the time of hydrogen bomb test.
ELECTRICAL AND ELECTRONIC FAILURE
Power blackout, telephone line failure, GSM cellular phone failure at Manhattan area was reported on and after 9-11. Firemen's walky-talky did not work, therefore, Commander could not tell them to evacuate from WTC. Digital camera and video recorded strange afterglow. All these can be instantly attributed to the electro-magnetic pulse caused by H. bomb while nothing to do with Thermite.  We, Japanese strongly believe Professor was hired by Jewish 9-11 perpetrators and his task is to avoid people to hang around "HYDROGEN BOMB" theory. Is that right?  If it is found hydrogen bombs were used at WTC,  it directly means 9-11 was a inside job. (It is indeed a inside job without doubt. As you know well.) Therefore, Professor was nominated to let people look at different and wrong direction of Thermite theory. Right? BYU is a university of Mormon Church. We know its close relationship with Jewish Mega Power. Founder of the church was a Jewish who converted to a Christian. But, we know many Jewish ostensibly do so and still maintain their old faith within their closed society.
POWER BLACK AT WTC OUT PRIOR TO 911
Dr. Lowenstein, if you were to bring the hydrogen bomb into WTC and set it at its basement, it would involve many workers who frequently go in and out and would be rather difficult to hide the job from third party's eye. Then, it seems you have arranged a power blackout on September 8 and 9. During these 2 days, both security lock and security camera were not in service. You could conceal your site job to plant the bomb inside. Right? Furthermore, the contractor in charge of supplying and setting WTC's security equipments belong to G. W. Bush's youngest brother. So you all stealth Jewish could freely proceed your terrorist activities.    
HOW DID YOU SOLVE NUCLEAR FUSION DIFFICULTY?
Dr. Lowenstein, your beloved Professor Jones who proposed Thermite thesis is originally a scientist specialized in low energy nuclear reaction (LENR) i.e., COLD FUSION, right? This fact makes us very curious. If LENR is really applicable as of today, it instantly means it can be applied to ignite nuclear fusion at pure Hydrogen bombs. It can be a small. compact device easily hidden in the basement of WTC. It can be even loaded on Bunker Buster Bomb. And we suspect Professor's real intension of bloviating Thermite thesis was to keep people away from the relationship between Hydrogen bomb and LENR. Is my imagination not too far? Did Professor Jones really manage to develop Cold Fusion technology?  
WTC SYNDROME, A MERE RADIATION HAZARD DUE TO NEUTRON?
People in N.Y. are making big noises for their bad health condition after 9-11 and they are explained by authorities that it was because of dust, fume and chemical they inhaled during WTC attacks. However, many have found the similarity of its symptoms with Gulf War Syndrome that was believed to be caused by D.U. "According to Sally Ann Lederman, Ph.D., of Columbia University's Mailman School of Public Health, who studied 300 non-smoking pregnant women in the New York Metropolitan area, pregnant at the time of the disaster, about 44% of the women who lived or worked within two miles of the World Trade Canter had babies who were smaller and with significantly lower birth weight than infants born to those further away. Infants born to those mothers who were in their first three months of pregnancy during the terrorist attack were born significantly earlier than infants whose mothers were at a later stage of pregnancy during the attacks." (Depleted Uranium and other Toxic Exposures by Rosalie Bertell, Ph.D., GNSH  24 April 2005)  This strongly suggests RADIATION DAMAGE. There are many report of detected radiation both at WTC and Pentagon just after 9-11.
 D.U. IS A SCAPEGOAT TO CONCEAL HYDROGEN BOMB'S EFFECT?
So, some believes the planes were loaded with D.U., i.e., Depleted Uranium ammunition or Missile of D.U. armored was used. However, the similar disease can be caused by hydrogen bombs. When nuclear fusion is made at pure hydrogen bomb, significant volume of neutron is produced. It can instantly cause radiation hazards on human. Then, naturally people would suspect use of nuclear bombs, but, will be kept silent as far as D.U. is given as a source of radiation.  Have you arranged to educate people to focus on D.U. and never think of others like nuclear bombs, Dr. Lowenstein?
UNUSUAL LEVEL OF RADIATION IS DETECTED AT WTC.
It was reported that unusual level of radiation was detected at WTC and Pentagon after 9-11. However, no further investigation and report was made. Small amount of radioactive is produced when hydrogen bomb is activated. However, its level is rather low, therefore, Geiger Mullar counter would indicate a slight increase of radiation value. Meanwhile University of California found elevated values of Tritium on 9/13 and 9/21 within bounds of the WTC. In pure hydrogen bomb isotopes of hydrogen are fused.  Tritium is a evidence of H.bomb explosion. Ordinary Geiger Mullar Counters would not detect Neutron ray while Pure Hydrogen Bomb's major source of radiation is Neutron. No one can feel it and detect it.    
 WAS HYDROGEN BOMBS USED WHERE D.U. WAS USED?
The similar disease is reported among Gulf War veterans, Iraqi citizens, returned soldiers from Iraq and WTC survivors. And Depleted Uranium ammunition is always blamed. Dr. Lowenstein, is D.U. really a reason for these sickness? Could we suspect you used Pure Hydrogen Bomb at Gulf War, Iraq war and 9-11 attacks?  Did you purposely use D.U. to hide the use of H. Bomb at all these destination? Did you, Dr. Lowenstein?
HOW DID YOU MANAGE TO CONTROL EFFECT AND DIRECTION OF H. BOMB?
In order to blow off WTC in the manner as you actually did, you would need to control the effect, yield and spreading angle of explosion. How did you manage it? In October 2001, an earthquake of Magnitude 3 was registered in Western Pakistan (Near the battlefield of Afghanistan) and it was reported by several media as a possible explosion of tactical nuclear weapon in the form of Bunker Buster bomb. Apparently normal iron bomb cannot cause such earthquake. However,  there was no record of higher radiation level at neighboring area . Thus, it was attributed to the sympathetic detonation of the bombs under the ground. But, Dr. Lowenstein, I tend to think of Pure Hydrogen Bomb. It can cause Magnitude 3 earthquake and never cause the increasing level of radiation at neighboring area. Didn't you use it there? If you have already manage to load the Pure H. bomb inside Bunker Buster, you can use the same for WTC attack. You can detonate the bomb upward instead of downward. Conventional nuclear Bunker Buster is already developed and its effect and spreading yield can be well controlled. If only you can use Pure H. bomb instead of ordinary one, you can use H. bomb to demolish WTC in deep secrecy. No one know it while they suffer for radiation hazard without knowing the cause.
DR. LOWENSTEIN, DID YOU AND YOUR FELLOW JEWISH WARMONGERS USE PURE HYDROGEN BOMB TO KILL INNOCENT AMERICANS AT WTC? If so, please pack up your belongings and cue up for the cargo train directed to the concentration camp located in the HELL as your ancestors were forced to do in 1940's by your fellow stealth Jew, Barron Adolf Rothschild Hitler.
