I am ignoring much of the pretext. Much like the Iraq War, I'm trying to focus on the real ideology and material factors driving the decisions, not the rationalizations designed for the public and the salons. Obviously this is not an exact process and there is no way to verify, so here we are.
Given there's a clear historical parallel (not identical, but appropriate enough) with the Cuban Missile Crisis and Monroe doctrine, I don't think it's rational to ignore the NATO "encirclement" argument as pretext. Look through the Wikileaks cables for all the talk of particular "neuralgia" over Ukraine entering NATO, and even talk of Crimea, all the way back in 2008.
One reason I'm so unconvinced this is pure pretext, is that I think it's highly unlikely that the same few people (Lavrov, Putin, etc.) would be making these specific claims and complaints in advance, just to be used a decade and a half later as pretext.
Another is that there are numerous high ranking people in the US foreign policy establishment, both in actual positions of power and attached to semi-official think-tanks, etc., that have agreed with their argument or at the very least identified it as sincere on the part of the Russian government.
As for me saying two wars, I was speaking about Ukraine only (depends on how you count, but I was counting Crimea, and the current invasion, though you could add another for the "breakaway" regions where Russian forces have been involved for years now). I'm aware of South Ossetia and Abkhazia, I think you and I might have already discussed those regions on HN in the past.
