That's what I mean by backward-looking. Putin is so obsessed with his perceived stature and "correcting" past humiliations that he's willing to create a completely fictional crisis and drive his country into a never-ending meatgrinder war just to prove some abstract geopolitical point.
This just goes to show how incomparable the situation is with the Cuban missile crisis. The US has nothing to remove, because their nuclear weapons stand where they stood 40 years ago.
