I suggest there is way more happening than a land fight between Ukraine and the Russian Federation.
@Bruce: I suspect you are correct - especially about more happening than the great unwashed (i.e. me, and perhaps you included) understand
The real problem is that by definition, an autocratic ruler like Putin is accountable to no one but himself and history has shown that the ambitions of a despot always transcend any consideration of the carnage and the citizens that must die to further his ends!!
The increase in rhetoric by Russia towards the use of nuclear weapons was to be expected - at this stage, Putin's threats have been accompanied by the adjectives "short-range" (missiles), but as we will both agree, escalation in stress situations is real easy - and with the current bunch of decision makers on both sides, I'm not at all convinced that MAD will be a sufficient deterrent for global participation.
Since I'm an agnostic and since you are more likely to succeed, I will leave it for your prayers to be heard that wiser-heads prevail - before the big-red-button is pushed!!
The other interesting matter to watch in this conflict is the question of so-called "targeted sanctions" - which is a thing that I believe to be an oxymoron. Targeted sanctions appear to be the 21st Century's alternative to armed participation in conflicts. But in truth, they are inevitably anything but "targeted" because they invariably leak-like-a-sieve.
A prime example of this is a few posts-up in which
@JMR complains about his heating bills. I doubt that statements from your President that the sanctions are targeted will be solace to the reality of the side-effects of these instruments.
And likewise, I suggest that anyone else is living in fantasy land if they believe that they won't be affected by the existing and yet to be announced new targeted sanctions. It's simply not possible in today's global economy to insulate the rest of the world from sanctions of the size anticipated (irrespective of the marketing label "targeted").
Even if the rest of the world avoids open conflict in this war, we ALL will be paying for the targeted sanctions -it's only a question of how much!
