Let me ask you a question.
When Obama wanted to strike Assad for using outlawed chemical weapons, were you for it or against it?
When Trump wanted to strike Assad for using outlawed chemical weapons, were you for it or against it?
See, I was for the strike. It didn't matter who proposed it. The banned chemical weapons had been outlawed after WWI. It was the Principle.
Now, I'm guessing you based your approval on WHO was proposing the strike.
