Ukraine's army was destroyed long ago. You can't build an army on the fly. The art of waging war has evolved and like in times past there are hard earned lessons. Russia is a formidable enemy. It's industry is working on a war footing. It's people are determined and troupes are well trained and equipped. The sensible thing to do is sue for peace and negotiate as best they can under the circumstances. Negotiating soon after this started would have been far more productive than it is likely to be now that it has gone on so long. This is a dilemma caused by a make believe President and an administration that has no idea how to nobly get out of the hole they've dug. Ukraine is led by an ex-exotic dancer placed in power by an Oligarch that had an axe to grind with Russia and a make believe American President that has everything to hide. Russia will grind Ukraine down until what's left of it's armed forces melt away.
