I've got to disagree with a couple of your examples: * MAD has proven an extremely effective tool for maintaining (relative) peace. It's almost certainly the only reason for the Russian Federation remaining an ongoing concern, and it's been the primary motivator for the continued existence of NATO, which is itself a stabilizing force. If you're a state that wishes to maintain independence, super weapons are a proven approach. * In the US, we're currently watching a backslide of all sorts of gains made over the last century. History is far from monotonic, and taking progress for granted is a surefire recipe for losing it. In the case of a full-blown regime change, it would not at all be a given that basic things like labor rights were upheld.
