The fuselages did indeed exist - but were for training Palestinian nationalists of the Abu Jihad faction (NB. This is not Islamic Jihad!) However, they subsequently had a falling out - to the degree that Saddam had Mr Jihad bumped off.
The US have no secret evidence - they revealed what had been their previously hidden evidence - the locaton of Osama-linked bases in Iraq. Strangely, they turned out to be in that part of Northern Iraq run by the Kurds and where Saddam has no power whatsoever. In fact they are part of the Northern no fly zone and so by the logic of the Pentagon the Marines should actually be attacking the White House and 10 Downing Street - since they are obviously protectors of Osama.
Saddam is not a nice chap - he is your basic Stalin clone with new improved fascism added to the mix. He was ever thus - even when the West set him up after removing the previously mildly pro-Soviet Baath faction. So that he has in common with Noriega, the Shah, the Afghan fundamentalists, Pinochet, etc, etc.
I like Americans and I am a Brit - I hope as few people as possible are killed in this farce (and thats what it is) as possible. Just remember - the 'war' isn't the difficult bit, the 'peace' will be the tricky part. Get that wrong and the Twin Towers will go down in history as Sarajevo was to the First World War.
PS. Just because we like porn doesn't mean that we don't know anything.
