We all have friends we disagree with, but Ellen deserves catching shit for palling around with a guy who started a war that killed nearly 5 thousand American soldiers and hundreds of thousands of civilians for absolutely nothing.
Is that something the US should be doing? I think not, and it frequently ends badly, but Presidents keep trying. Like Obama in Libya or the elder Bush and Clinton in Somalia and Bosnia.
Bosnia was different. Clinton was 100% correct (and too slow) to act, because it was genocide. He already Rwandan blood on his hands by his inaction.
Ironically, she didn't catch flack for George being president of the Iraqi war, she caught flack for George's stance on LGBT issues when he was president.
Not all of us lied to get Congressional authority to use force with explicit conditions, and not all of us declared those conditions to be met and applied the force so authorized in knowing bad faith.
In fact, exactly one of us did that, and his name is George W. Bush.
Whatever guilt anyone else has in that matter is far less.
