Russian, U.S., Ukrainian and EU officials forged a deal yesterday to “de-escalate” the crisis in Ukraine. Pro-Russian separatists must disarm and quit the buildings they occupy but will be granted amnesty. In exchange, Ukrainian officials have agreed to talks on constitutional reforms that could spell greater autonomy for those in the east. President Obama said he was cautiously encouraged by the news. But there’s been no indication pro-separatists plan to comply. And in a disturbing development, fliers have appeared in the city of Donetsk ordering Jews to register and pay a fine or face deportation.
