About when did a US/CCCP war become suicidal?

AIR, the "dew line" was established to give us 20 minutes notice of inbound
Soviet missiles, wasn't it? If so, I think the actual time when MAD became our
joint policies would have been in the middle fifties, or perhaps even a little
bit earlier, to coincide with our government having learned that the Soviets had
stolen our nuclear secrets and were acting on them.

The DEW line was for air-breathers (bombers in those days) now replaced
by North Warning.

BMEWS (Ballistic Missile Warning System) was the missile warning system
based in Alaska, Greenland and the U.K.
