Putin should know what miscalculation looks like.
Yeah, I am sure he sees it all the time coming from American neocons.
I don’t really think he miss calculated in going into Ukraine. He had two choices. Do nothing and watch as NATO militarized the entire border of Ukraine with NATO forces, and ultimately attacked Crimea and turned Sevastopol into a NATO Navy base. Then standby idly as the Banderist Ukrainian military completed their ethnic cleansing in the east.
OR option two, he could take the action he did, as much as it sucks, and hope for the best. So he was left with a bad choice…,and a really bad choice. But it’s not a miscalculation. Because if he accepted the first option, there would never be any undoing it.
Hopefully his action winds up destabilizing and weakening DC as a side benefit.
