China, in the future, is going to have even more nuclear capability than it has had in the past. I don't believe that they have anything to fear from the United States, and I frankly don't believe they do fear the United States.

History is just littered with problems that were solved that were supposed to be impossible.

The most striking thing is that even before Osama bin Laden was killed, he seemed largely irrelevant to the Arab Spring.

Donald Trump seems to be unconcerned about the Russian aggression in Ukraine. By doing this he tells them that they can go ahead and do what they are doing. That is dangerous.

I mean, we're going to probably debate the Iraq war for at least as long as I'm alive.

Poles understand perhaps better than anyone the consequences of making toothless warnings to brutal tyrants and terrorist regimes.

It would be a huge mistake to abandon democracy promotion. Peaceful political change has been enormously successful in the past years in Eastern European countries as well as in countries like South Korea, South Africa, Chile and Indonesia. However, if possible, the use of force is something to avoid except in cases where genocide is threatened, like Bosnia or Libya or with regimes that threaten our security, like the Taliban and Saddam Hussein.
