China will be looking at the Siberian oil fields and thinking about protecting all their ethnic brothers and sisters.
Ugly thought, but they surely want Vladivostok back. Long-term bone of contention that they finally settled formally. Doesn't mean they won't go grab it, if they sense weakness.
And the military police force under arms in Russia numbers? Plus air force etc? A few more than 25k I'd imagine.
Numbers are one of those things that matter more on paper than they do in practice, with the number of troops under arms. Twenty-five thousand battle-hardened veterans are worth a lot more than the same number of green recruits, poorly-trained reservists and converted police. The score at Agincourt was something like ten-to-one or better in favor of the English.
Then there's the most elite of the world's special forces, who can stroll into a command post, kill everyone there and stroll out whistling a tune without a scratch on them. It's important to compare both how many, and who, when assessing capabilities.
