Ukraine needs man portable anti tank missiles. Pakistan was willing to sell their TOW missiles to Ukraine, but that would have required the US approval. General Breedlove pushed for the White House to give it and that is why he was sacked.
So, what, a hundred anti-tank missiles will make them safe? A thousand? Ten thousand? Is that all that is missing from peace in Ukraine?
Ukraine needs energy and economic independence from Russia. They need business development dollars and a method to move forward. A low degree war with Russia's proxy fighters going against the US proxy fighters won't bring any of that.
