The problem isn't that Cuba has a communist government. It's that we used to own Cuba. So it's stolen property now, and we're sore about losing it. But we never owned China.

Sure, the Brits used to own China, and we own them now, so in a sense you could say we used to own China. But that's a long time ago... water under the bridge. And even with Cuba I guess we must be starting to get over it, starting to talk to the thieves who stole it from us.
