Lest we forget the Cold War
Those of us who lived through the Cold War remember what it was like to wake up every day to the threat of nuclear destruction and MADD (mutually assured destruction).
In the 60's we had air raid siren drills once a month, in the middle of the country no less. We remember the anxiety around the Bay of Pigs and the Russian missles stationed so near our doorstep.We remember the duck and cover drills as children, no matter how ridiculous they seem now. We remember the pictures of the tanks rolling into the Eastern European capitals as the Soviet threat expanded. All these things are part and parcel to Baby Boomers mind set.
Since the fall of the Soviet Union, the fall of the Berlin Wall, the new generations have not had to live under the spectre of mutually assured annihilation (even if it were overblown by politicians at the time). These new generations have not had to feel the oppressive weight of an enemy that posed an intrinsic threat of complete human destruction.
Yes, you had 9/11, but it was a one time event that would not destroy an entire nation. Al Queda was never an intrinsic threat for the elimination our our entire nation. It is an important threat to address and ameliorate, but does not form a daily worry in the majority of our lives.
My point: Trump's exit from the IMF is problematical. The thought for Baby Boomers of a return to another arms race akin to the Cold War is not acceptable. Nuclear proliferation is not joke. The reality of living once again under that spectre of planet level destruction I suspect will not find a lot of support from my generation. At least I would hope not.
Our present Commander in Chief is not intellectually prepared for this type of challenge. He neither reads his intelligence briefs, nor listens to his advisors. He demonstrated during his candidacy that he has no concept of what a nuclear weapon is, or what its potential can be. An arms race as this juncture, with this president is even more perilous than what we Baby Boomers faced.
