Who are the stateside policy wonks so insistent on reviving the Cold War over Ukraine?

The powers with the most skin in the game?—?France, Germany, Russia and Ukraine?—?have agreed to a shaky truce. The accord, reached on February 12, outlines the terms for a ceasefire between Kiev and the pro-Russian, breakaway provinces in Eastern Ukraine. It envisages a withdrawal of heavy weaponry followed by local elections and constitutional reform by the end of 2015, granting more autonomy to the war-torn regions bordering Russia.

But not all is quiet on the eastern front. Kiev alleges that the ceasefire has already been undermined. An almost identical compromise, reached in September, broke down soon after.
