He invaded and occupied Iraq under false pretenses. That sounds like a war crime to me. Look, Bush did not say "Iraq might have WMDs" or "we believe they have WMDs but I could be wrong" he said "Iraq has WMDs" that, along with the myriad of other lies and backhanded deals to his buddies and members of his administration is the reason Bush gets dogpiled. You cannot name a worse President in modern times, not even Carter.
EDIT: I also want to add the bullshit "Faith Baised Initiatives" he started. While this doesn't pertain to him being a war criminal it does (along with the PATRIOT Act) show that he used the Constitution as mere toilet paper.
It's not false pretenses if he actually believed Saddam had WMDs. It's a fact that Saddam refused to allow any more U.N.
inspectors in and it just made perfect sense at that time that Saddam had WMDs. To say nothing about
him being a state sponsor of terrorists. And as we appear to be repeating the same thing over to each other I guess we'll just have to agree to disagree. As for Bush being given credit for Osamas death is the fact that Obama has largely carried on the Bush foreign policy,
despite the fact that he attacked Bush as a senator and candidate for the same thing he now does! Don't get me wrong, I'm happy
that Obama gave the order that he did, but his overall foreign policy is rather hypocritical.
