@markcobb I mean, first, that isn't even true. There are multiple other countries in Europe that were previously part of the USSR.
And as for Putin, honestly, I find your faith in his word surprising. He's a former KGB agent whose critics routinely end up dead in violent and suspicious circumstances.
He wants power and glory. To believe anything else is to be deeply, deeply naive, in my opinion.
@markcobb I see your perspective, but I see things differently.
IMO invading Ukraine was a mistake, but Putin's not a reckless man. He expected to win.
But now he needs to win. Otherwise he risks his position at home to say nothing of his ego.
Which is why all-out nuclear war is off the table. Because if Russia is ashes, if he is ashes, he doesn't win. He's a corpse.
Why destroy yourself when you can simply threaten nuclear war and reap the rewards without doing anything?
IMO, anyway.
