“Ukraine doesnt have the manpower to fight the way they are fighting...”
Yet, they’ve been pretty successful, all things considered.
“...but continue to do it until troops fro other countries come in at force.”
That’s not going to happen and Ukraine knows it. And, I suspect, so do you.
Im not sure how many “contractors” are available to operate technical equipment in Ukraine. If they could get operators for all the advanced weapons NATO is willing to send, it may make a difference.
