What is Russia trying to accomplish? Dmitri Trenin tries to make sense of Russia’s actions in Ukraine:

In Moscow, there is a growing fatigue with the west, with the EU and the United States. Their role in Ukraine is believed to be particularly obnoxious: imposing on Ukraine a choice between the EU and Russia that it could not afford; supporting the opposition against an elected government; turning a blind eye to right-wing radical descendants of wartime Nazi collaborators; siding with the opposition to pressure the government into submission; finally, condoning an unconstitutional regime change. The Kremlin is yet again convinced of the truth of the famous maxim of Alexander III, that Russia has only two friends in the world, its army and its navy. Both now defend its interests in Crimea.

What will it cost Russia? Peter Baker reviews the limited options that the U.S. has to penalize Russia for its incursion. Helena Yakovlev-Golani and Nadiya Kravets run through different scenarios for Crimea’s future status (annexation, independence, status quo) and what each one will cost Russia over the long term.
