如果真的停不下来, 美国可能就正式提供武器了。 那就有得瞧的了。 http://www.nytimes.com/2015/02/15/world/europe/us-says-images-s ARTEMIVSK, Ukraine — A fragile, European-brokered cease-fire deal for Ukraine appeared at risk of unraveling, at least in part, when a rebel leader announced Saturday night that he would not be bound by the accord on a central battlefield of the war. Although the Ukrainian president and the rebel leader both announced that the cease-fire had gone into effect, the separatist leader said it did not apply to Debaltseve, where thousands of Ukrainian troops have been under siege and might be surrounded. The rebel leader, Aleksandr Zakharchenko, said the town, a critical railway hub, had not been mentioned specifically in the cease-fire agreement.
