On some level, if Russia is ever going to try to take Ukraine and China is going to take Taiwan --> has there ever been a better time? We're the weakest we've been in a long time, we have a puddinghead as president (how much he's in charge is open to debate), we gave up Bagram for no damn reason, and both Russia and China have long-term structural problems that are only going to get worse.
If Russia and China both seize territory at the same time, it works to both their advantage (I mean, other than putting the world at the precipice of WWIII).
