I wouldn't give up on Russia. I think they have legitimate security concerns from Islamic fundamentalism, not only on their border but in their country.

I don't think Hamas will be satisfied simply ruling the Gaza Strip.

I think the future of China's unknown, I don't know what direction it's going to go in. It could go in the right direction, it could. It could go in a very bad direction, too.

There is no patriotic obligation to help advance the career of a politician who is otherwise pursuing interests that are fundamentally antithetical to your values. That's not the call of patriotism.

If Iran obtains nuclear weapons, then almost certainly Saudi Arabia will do the same, as will Egypt, Turkey and perhaps others in the region.

The solution to North Korea is the reunification of the Korean Peninsula. China could influence the North; it supplies 80 to 90 percent of North Korea's energy. The United States have to put pressure on China in order for China to pressure North Korea.

Iran is barely over 50% Persian, and Arabs, Baluchis, Azeris, Kurds and many other groups feel left out of the society. That regime has a lot more weaknesses than people see.
