Hum. As always, things are relative. Growing up in the 1970s and early '80s I gave myself zero chance of ever reaching 30 (or even 25). Near miss scenarios were just too frequent. (E.g., compare the "Able Archer" crisis of 1983. The GDR had actually mid-range nuclear strike bombers on the runway with turbines running, ready to retaliate, and the USSR had forces moved into mobilization zones, ready for the worst.) Compared to this, things have become much better. However, the idea of the potential for any nuclear crisis scenarios being "solved" is as accurate as, say, the current idea of natural language recognition being "solved".
