qa, why exactly was regime change more important in Iraq than in North Korea? Surely you are aware that North Korea was well on its way to developing nuclear weapons in 2003, when the US declared war in Iraq (they’ve since exploded weapons equivalent in power to those that destroyed Hiroshima and Nagasaki). There is no evidence that Iraq was close to developing them in 2003 before the US declared war, and no evidence of nuclear weapons was found afterwards either.
just for the record, there is minimal if any connection between Hussein and/or Iraq and 9/11. Saddam Hussein did not have contact with Osama bin Laden, and in fact Hussein considered bin Laden an enemy (the CIA knew this in 2002). Yes, Hussein did fund the families of Palestinian suicide bombers; so did the Saudi royal family (the Israelis found documents detailing these payments during Operation Defensive Shield). And while 15 of the 9/11 hijackers were from Saudi Arabia, none were from Iraq. Do you think that the US should declare war on Saudi Arabia? (I don’t).
