Russia has long had its eye on the Crimea, and unsurprisingly, after decades of ethnic cleansing of Ukranians, the Russian language and ethnicity predominates the region. However, how would we feel should Mexico attempt to claim soverignty over majority Mexican/spanish speaking areas in the U.S.? We would not tolerate such a blatant violation of our borders or sovereignty, and nor should Ukraine. Hitler himself used the excuse of german ethnic majority to annex Sudetenland. Putin has attempted to exercise similar actions to "protect ethnic Russians." It's a land grab plain and simple...same as it was before WW2.
