If you're going to bring up Israel and the area around it, I was just looking at Wikipedia's page on wars involving the PRC, which reminded me (if I ever knew) that Tibet has been annexed to the PRC for just about the same time that modern Israel has been around.

I think it's worth mentioning that the US has not always been the preeminent ally of Israel since its founding. A lot of people seem to just have this vague sense that it's always been the situation. It's something that happened relatively recently.
