If you're considered an enemy of the state you're not safe on any side. Some countries terrorize their own people, others terrorize someone else's people. As I said in the past, after moving between democracy and dictatorship several times in my life I can say that it mainly boils down to how well your interests align with the interests of the one(s) in power. The main difference is that if your interests don't align you'll have a much harder life in a dictatorship than in a democracy.

But don't think for a second that the US won't force a diplomat's plane to land even outside their jurisdiction just because they believe an enemy of the state is on it. It's all about interests.
