I’ve often said that global climate change is an issue where no one has the luxury of being “half-pregnant.” You either are or you aren’t. And so it is with climate change. You either understand and accept the science – or you don’t. Folks this isn’t a cafeteria where you can pick and choose and accept the science that tells us what is happening, but then reject the science that warns us what will happen.

If Russia is there [in Syria] alone fighting them [ISIL], guess what? Russia becomes the target and Russia starts seeing - who knows - MANPADs will find their way in there, airplanes will fall out of the sky. They will become vilified. They'll become the new magnet, together with Assad, for the jihadis.

You cannot bring peace in Syria as long as [Bashar] Assad is, in fact, there.

It's hard to say that something is legitimate when a whole portion of the country can't vote and doesn't vote.
