Well, it's typical. The USA is the only great power that ever gets to have a military base on the soil of one of its official enemies. Can you imagine the Russians or the Chinese getting away with having such a base in Mexico? Or in Israel? Or in Canada?

No?

Well, of course not! The Russians are not God's official agent on this planet, and you must remember that. ;-) God's official agent here can do anything he wants, and the usual rules that would apply to others simply do not apply to him.
