MOSCOW (AP) — Russia will perceive any ballistic missile launched at its territory as a nuclear attack that warrants a nuclear retaliation, the military warned in an article published Friday.

Serious stuff because now an "accidental error" could lead to a mushroom cloud in Cali, DC, or little babylon.
