About when did a US/CCCP war become suicidal?

I was wondering at about what point that the United States going to war with
the Soviet Union become an almost certain act of mutual destruction. I'm
assuming it sometime in 1960's or 70's, since what I've seen of the Soviet
nuclear capability before that point doesn't seem to be all that
threatening. It looks like they would have been really bad for us
Americans, but not unsurvivable.

Even now it is survivable. According to different esimates
some 10-20% of population of each country have some chances
to survive even in full scale nuclear war. But the damage
is simply unacceptable for both sides. As far as I understand
even one bomb explosion in center of a big city in US or Russia
is totaly unacceptable for any side.
