I have thought this was a terrible idea since we started it in 2014.
When my two voting age children challenged me in November 2016 about my upcoming vote for Donald Trump, I told them it was a chance to avoid nuclear war with Russia.
Things get worse and worse. Hopefully, capitulation of the Zelensky regime will happen before interdiction of US supplies to Ukraine becomes necessary.
Why would that put an end to anything? The rocket is launched, the die are cast, choose your metaphor - the USA/NATO are at war with Russia. There will be another front. You can bank on it.
