The Crimea was taken by military force and occupied. The people that lived there did not vote to become part of Russia of their own free will.
Russia took the Crimea, waited a time, then attached Ukraine again for more of the Ukrainian territory and resources. Whatever, deal is made with Russia, they will just come back for more territory and even beyond the Ukraine borders.
Russia is not entitled demands for Ukraine territory of any kind.
Ukraine should stick to its position and fight to the death, if necessary. NATO – and – America as well as many other countries should help Ukraine in its fight. America should be supplying high level weapons to the Ukraine.
America bitches about money and cost cutting and then spends the money foolishly and wastefully anyway.
