[Bashar] Assad has made a series of choices ever since then that is literally destroying his country.

I promise just to serve two terms. Republicans do it differently. They just have the son repeat the father's whole first term.

We do have to take the long-term view. And long term, the question to ask ourselves is whether America should attack others pre-emptively, whether she should embroil herself in wars far away from our soil, and try to bring democracy by force to the rest of the world.

The Reagan Administration has no rational plan for our military. Instead, it acts on misinformed assumptions about the strength of the Soviet military and a presumed 'window of vulnerability,' which we now know not to exist.

We do not need to divide America over who served and how. I have personally always believed that many served in many different ways.
