Russia issued what appeared to be a veiled warning to the U.S. and other Western nuclear powers that failure to refrain from certain “provocations” can result in a nuclear catastrophe…Russia’s Foreign Ministry released a statement “on the prevention of nuclear war” on Wednesday, calling on other nuclear powers to “abandon dangerous attempts to infringe on each other’s vital interests, balancing on the brink of direct armed conflict and encouraging provocations” with weapons of mass destruction (WMD). Such provocations, the ministry said, “can lead to catastrophic consequences.”
