Russia may answer conventional attack with nukes

A Russian Cabinet member says Moscow has reserved the right to use nuclear weapons in response to a conventional strike.
Today's comments by Deputy Prime Minister Dmitry Rogozin carried by Russian news agencies reflected Moscow's concern with prospective US weapons.
Weapons that have been developed in the US under the so-called "prompt global strike" program would be capable of striking targets anywhere in the world in as little as an hour with deadly precision. Russia, which has lagged far behind in developing such weapons, has described them as destabilizing.
Without naming the US, Rogozin said that those who "experiment with non-nuclear strategic weapons" should remember that "if we come under attack, we will undoubtedly use nuclear weapons in certain situations."

He described nuclear weapons as a "great equalizer.
