On 6 October 1979, General Secretary L.I. Brezhnev bunched a surprise diplomatic offensive against the West with a proposal to negotiate a theater nuclear arms control agreement for Europe. He offered in his speech at East Berlin to enter into immediate talks, but with the stipulation that the North Atlantic Treaty Organization (NATO) muse not upset the current balance of power in Europe by deploying a new generation of American-made long range theater nuclear forces (LRTNFs).
