> ... if we boil it down, there are really only two paths toward ending the war: one, continued escalation, potentially across the nuclear threshold; the other, a bitter peace imposed on a defeated Ukraine that will be extremely hard for the United States and many European allies to swallow.
Considering some of the calls from those who should know better for no-fly zones over Ukraine, Option (2) is indeed going to be the harder path. All it would take is a humanitarian incident such as the extended siege of a city. The calls for military action would be ferocious. The accusations of weakness would cripple many leaders trying to hold back a military response. The lack of any sense of what nuclear escalation actually means throws yet more fuel on the fire. And the real clincher: the US hasn't taken on a power capable of defeating it since the 1940s, if not earlier. Confidence in the US military to solve all problems, foreign and domestic, is alarmingly high.
The easy path is, unfortunately, the one that ends with the unthinkable.
