Democrats proposing success in Iraq by political solution.

And if [Vladimir Putin] does fight ISIL alone, how does it work out for Russia to have sided with Assad, sided with Iran, sided with Hizballah, when they're trying to reach out to the rest of the Sunni world in the region? That's not a good equation for Russia.

I accept that friends of ours have decided that the President's non-strike has somehow impacted perceptions of us. But I believe they are dead wrong and I think the critics are dead wrong, and here's why. The President [Barack Obama] made his decision to strike. He announced his decision to strike publicly. And the purpose of the strike was to get the chemical weapons out of Syria. That's the purpose.

Just the fact that we can't pass budgets in our Congress, just the fact that we are gridlocked in our own democracy, the fact that everybody who travels can see that we're not investing in our airports, in our rail, in our infrastructure and so forth, people are noticing a United States that is not getting the job done in some ways.
