In a word, as much as they abhorred the brutal Soviet repression of the Hungarian uprising in 1956, the Prague Spring in 1968 and the solidarity movement in Poland in the early 1980s, among many other such incidents, they did not threaten war for one simple reason: These unfortunate episodes did not further endanger America's national security. Instead, in different ways each of these Presidents searched for avenues of engagement with the often disagreeable and belligerent leaders of the Soviet Empire because they "felt that America could not remain isolated from the rulers of the world's largest nation".

Accordingly, during the entire span from 1933, when FDR recognized the Soviet Union, until 1991, when it ended, the US never once claimed Ukraine's independence was part of its foreign policy agenda or a vital national security interest. Why in the world, therefore, should we be meddling in the backyard of a far less threatening Russia today?
