Ukraine is not a vital interest to the West nor NATO, but it is to Russia, and short of WWIII which generates a very real risk of a nuclear exchange in Europe the situation in Ukraine is not changing. This is the same opinion Barack Obama held in 2014. People need to think about this on a timeline longer than their emotional attachment to this issue demands.
Recall when prominent American leaders, Hillary Clinton among them, demanded a NATO enforced no-fly zone over Syria as an addendum to arming Islamists in the country. This absolutely would’ve resulted in NATO and Russian direct combat, and with it war. Cooler heads prevailed then and I pray they do so now.
