not everybody wants to start WWIII over a non-NATO country.
That's why this should be a UN operation, and not a NATO action. Although it affects European stability, strictly speaking it does not involve them.
Well they are unlikely to get a security council resolution through, given that Russia has a veto there. They learned their lesson more than 70 years ago when they (well, the Soviets) were boycotting the UN, and the Korean war resolution got through because they weren't there to veto it (and China's seat was held by the ROC, which is the reason the Soviets were boycotting it).
Apparently there is a bill going through the US congress calling on the UN to kick Russia of the security council; then they wouldn't have a veto any more. This could be done by amending the UN charter, but any amendment must be agreed to by all permanent members of the SC, which I consider unlikely given that Russia is one of them.
But I don't see why a SC resolution is needed, this looks like a pretty clear case of defence, not like 2003 when the US and the UK "defended" themselves against Iraq, or now, when Russia is "defending" itself from Ukraine.
But the big players don't seem to have their hearts in it. Some of them announced in advance that they wouldn't be fighting in Ukraine, which probably wasn't the best way to keep Russia from invading. I think Ukraine will not lack for foreign assistance when it comes to weapons and supplies, but they will probably have to do the bleeding themselves.
This whole thing makes no sense at all. It is immensely unpopular in Russia. The president has made his career keeping the moneyed classes happy, but they're not going to like this one. Huge protests in St. Pete's also. Russia hasn't had a "colour" revolution yet, but maybe it will now.
And the force is too small for a sustained occupation. What are they going to do, take Kyiv, put in a new government, and then leave? The last pro-Russian president was overthrown and now lives in Russia. Maybe any new government (if Russia even takes Kyiv) can last longer. The government they left behind in Afghanistan lasted 2.5 years (the one the Americans left there lasted about a week). If they want the any new government in Kyiv to last, they're going to need more muscle than this. And if that's not the objective, then I don't know what is.
Well Russia's military performance in Grozny in the 1990s and in Georgia in 2008 was so bad it was embarrassing. They've upgraded a lot since then, but so has Ukraine. Crimea went down without a fight in 2014, but that's a place where there is very strong pro-Russian sympathy; the rest of Ukraine isn't like that.
I used to think that although Putin might be ruthless, he wasn't a moron. I'm having to reassess that now.
If Putin wants to bomb someone, he might want to take lessons from the Americans. They just bombed Somalia again, and hardly anybody gives a rat's arse, or even knows that it happened. But when you bomb Europeans, people get upset.
