I think I know where Krill K is going with his ranting, I think he is talking about the five Japanese mini-subs that slipped into the harbor, nine out of the 10 men on board these minisubs died, whether they were meant to be suicide attacks is unclear, the subs did have the capability to head back to the fleet, but in reality that was unlikely in a harbor on lock down. Hell, one of those subs were sunk upon trying to enter the harbor one hour before the attack. But these were not kamikaze's, the mini-subs were armed with torpedoes, they were not meant to just simply run into the boats, in fact I think they all failed in their objectives and sank, except the one that washed up on shore.
The thought that Japan could be responsible for the attacks of 9/11 is ludicrous, Japan's economy also suffered from the attacks, the United States' greatest trade deficit is greatest with Japan over that of any other nation. I also heard that some Palestinian Terrorist group had claimed responsiblity for the attacks of 9/11, but Al Qaeda is the only terror group that had the ability to pull it off, the US would have seen this attack coming from any other nation, we have spies or informants in all the governments that could have pulled this off, but then again the same is most likely true in the other direction. The evidence before and after the attack all pointed towards Al Qeada, Osama Bin Laden is responsible for the attacks, heck, he had a history of such actions.
