Any time we give people the ability to use force, we have to be very careful. It's sort of like the people who spy on us - you've got to watch the watchers.

I've introduced legislation to say, "For right now, let's stop it," from about 34 countries.

The separation of powers is about legislative powers. It isn't about discussion or words.

I think that, most importantly, when I see issues of war, I see them in a personal vein, and I am reluctant to go to war unless there's a real, valid American interest because I've seen the wounded soldiers.

I tell people I won't vote to go to war unless I'm ready to go or send my kids.

I think it's a conundrum. If we have no laws on this, people take it to one extension further, does it have to be humans, you know?

I think that there is a bipartisan consensus that's incorrect that we should have the whole world be in NATO. For example, if we had Ukraine and Georgia in NATO - and this is something McCain and the other neocons have advocated for - we would be at war now because Russia has invaded both of them.
