Our patience with Russia? Perhaps they are losing patience with what they perceive as western interference in Ukraine. I am not entirely unsympathetic with the wishes of either the majority in Crimea, or Putin’s stance on the matter.
I see some difficult elements among those who have forced a change of government in Kiev, and, TBH, the least messy option is to allow the peaceful secession of Crimea rather than confront Russia over the region.
Ukraine is bankrupt, systemically corrupt, and light years from the stabilising influence of EU membership. I can perfectly understand why Putin does not want another unstable republic snapping at his borders.
America (and ourselves) are lucky to be bordered principally by ocean or highly stable countries. Easy to make pronouncements about democracy in those circumstances.
