Some of the comments on the link by James_Miller exactly six months ago provided very specific estimates of how the events might turn out:
James_Miller:
- The odds of Russian intervening militarily = 40%.
- The odds of the Russians losing the conventional battle (perhaps because of NATO intervention) conditional on them entering = 30%.
- The odds of the Russians resorting to nuclear weapons conditional on them losing the conventional battle = 20%.
Me:
"Russians intervening militarily" could be anything from posturing to weapon shipments to a surgical strike to a Czechoslovakia-style tank-roll or Afghanistan invasion. My guess that the odds of the latter is below 5%.
A bet between James_Miller and solipsist:
I will bet you $20 U.S. (mine) vs $100 (yours) that Russian tanks will be involved in combat in the Ukraine within 60 days. So in 60 days I will pay you $20 if I lose the bet, but you pay me $100 if I win.
While it is hard to do any meaningful calibration based on a single event, there must be lessons to learn from it. Given that Russian armored columns are said to capture key Ukrainian towns today, the first part of James_Miller's prediction has come true, even if it took 3 times longer than he estimated.
Note that even the most pessimistic person in that conversation (James) was probably too optimistic. My estimate of 5% appears way too low in retrospect, and I would probably bump it to 50% for a similar event in the future.
Now, given that the first prediction came true, how would one reevaluate the odds of the two further escalations he listed? I still feel that there is no way there will be a "conventional battle" between Russia and NATO, but having just been proven wrong makes me doubt my assumptions. If anything, maybe I should give more weight to what James_Miller (or at least Dan Carlin) has to say on the issue. And if I had any skin in the game, I would probably be even more cautious.
But you also have to remember that there is not the history between the US and these other regimes the way it is between the US and Russia. Putin is an old communist and he remembers the old days, he remembers them very well and he wants them back. Putin and his cronies chafed in the 90's under Pax Americana and now they have their chance to shake up the international order rather than conform to the American lead way of doing things and I think he is of the opinion that if it doesn't happen now there won't be another chance for a generation.
