I am deeply concerned about the kind of people Hillary Clinton's surrounded herself with in the past.

We have an even worse situation in Syria, where the United States' allies are actually supporting people who are violently opposed to the United States, who are dangerous, radical Islamist fanatics. I mean, where is the logic of that? When are we going to call the Saudis on the support of intolerant, bigoted, fanatical types of Islam? When are we going to call this ally?

Russia and Iran are not going to allow the Assad regime to fall.

Donald Trump is unpredictable.

President Bush Sr. and Secretary Baker, way back when, told Gorbachev, "We are not going to advance NATO into Eastern Europe. We're not going to - we're not going to advance NATO into East Germany, if you allow the unification of Germany." Where is that pledge? Where is the logic behind a military alliance, devised in the time of communism, before the Berlin Wall fell, now being in the Ukraine, in Poland, in Estonia, in Latvia and Lithuania? I don't understand.
