Iraq has no history of ethnic conflict.

That sense of what happened in Europe in World War II has shaped a lot of my views.

If a cat sits on a hot stove once, it will never sit on a cold one either.

It's hard to conceive that it would take more forces to provide stability in post-Saddam Iraq than it would take to conduct the war itself and secure the surrender of Saddam's security forces and his army. Hard to imagine.

Donald Trump seems to be unconcerned about the Russian aggression in Ukraine. By doing this he tells them that they can go ahead and do what they are doing. That is dangerous.

Putin is behaving in a very dangerous way. And Donald Trump sounds as though he would simply sit back and allow that to go on. I worry about where that would end up.

If the Arab world today looked like Tunisia, it would be a huge blow for the extreme ideologies. But Tunisia needs more support than it is getting, particularly from their close neighbors in Europe who have a great stake in North Africa.
