The downing of Malaysia Airlines Flight 17 over Ukraine, apparently by Russian-trained separatists using a Russian missile launcher. The US government’s determination that Russia has violated the Intermediate-Range Nuclear Forces Treaty of 1987 by testing ground-launched cruise missiles. Increasingly stringent US and European economic sanctions against Russia’s government and key areas of the country’s economy.

Fear is fueling actions on all sides, even leading Russian Deputy Prime Minister Dmitry Rogozin, in a speech on the country’s July 27 Navy Day, to laud new nuclear submarines being built at Severodvinsk, saying they will be a reliable deterrent against any threat: “We see the presence of a nuclear potential can cool the fervor of any aggressor located at any point in the world.”
