The other thing I said is the great irony is you will be back fighting against your own weapons. Had [Bashar] Assad been bombed when he used chemical weapons two years ago, ISIS would be in charge of all of Syria now.

Are you so afraid that you are willing to trade your freedom for security?

What most Americans don't realize is there is an unholy alliance. They come together. There's a secret handshake. We spend more money on everything. And we are not stronger nation if we go further into debt. We are not projecting power from bankruptcy court.

I am encouraged President Obama now says he will fulfill his constitutional obligation to seek authorization for any potential military action in Syria. This is the most important decision any President or any Senator must make, and it deserves vigorous debate

[John] Bolton was an advocate for regime change in Libya, so was Hillary Clinton actually. And Donald Trump said it was a mistake. I agree it was a mistake to do regime change in Libya. We became more endangered and actually worse people took over afterwards.

I do want to see an immigration compromise. And you can't have an immigration compromise if everybody's out there calling the president a racist.

The idea of foreign policy realism, I think, fits more neatly with President Trump. And with John McCain, the neoconservative label of let's make the world safe for democracy and we're going to topple every regime hasn't worked.
