Ukraine crisis escalates as Russian and Ukrainian troops mobilize for a possible war in Crimea. The US and EU threaten sanctions as Russia uses its natural gas dominance as leverage over Ukraine and the West.
Putin justified a military action in Ukraine's Crimea as necessary to 'protect' Russian 'compatriots.' Such aggression based on an ethnic card can be easily challenged by the US and Europe.
The strategy of the West regarding Russian aggression in Ukraine should be to complicate Vladimir Putin’s planning. He should be given options to avoid conflict. But he should also be made aware of the negative consequences for Russia that would follow armed conflict.
