It is massively fucked but… they probably should.

This war is ending in March or April one way or another. Europe/NATO have committed to supporting Ukraine. The US is almost guaranteed to actively betray them. And you can bet the EU and the like are going to be consolidating resources in fear of whatever else comes up.

So Ukraine needs to win NOW. It is probably already too late to meaningfully train those conscripts but having a military force that can act in that small window of late January is basically their only hope.
