anybody can cherry pick anything. now pick one of the countless games that failed.   russia walked in, grabbed ukraine's eastern border, building a land bridge to crimea, and have been steadily expanding it ever since, no matter what the west has done to stop the bleeding. the only way to get that territory back and prove that world borders are frozen rather than subject to change as russia proved, is to get involved directly. there is no other way to get that land back, and even then it would fail.
