Counter-culture had many dimensions, namely music, art, dress, and anti-war sentiment. As I remember it, war protests were the most vocal. When people demonstrated on campuses, they were against the Vietnam war. The fifties saw an "incomplete" teaching of Nuremberg and ex post facto that gave the young men the notion that they should be able to say no to military service if the integrity of the country was not at stake. With respect to war protests, they ended rather suddenly in 1973 when the draft ended and the war was winding down. It was as if the young generation was saying "thank you" and they went about living. Soon, fuel shortages and high inflation would bring in an era that didn't react much the counterculture that shaped the end of the sixties.
Going to disagree on your take on Nuremberg. Germany was a defeated nation, the atrocities committed were beyond the pale. The Germans themselves changed laws post ex facto to give legal precedence to barbaric murder. They also broke every agreement ever made between Nazi Germany and the world as a whole.
No one liked the draft. After world war 2 the USA sized down. Scaled back up for Korea and the cold war, jumped into Vietnam. By Vietnam, noone understood why we were there, why were we fighting in jungles with no end in sight.
There was an end to Korea.
Anger at old ways that no longer made sense, the ultra conservatives, the church, the old staunch guard that didn't want to change.
The end of world war 2 created the following:
Women working, and contributing as well as men - after the war told to go back and play dolls and raise kids..
Minorities fighting again for a nation that treated them as second class - then after the war and sacrifice, treated like second class citizens
The war saw the begining of the end for empires - the British and French and Portuguese, dutch and Spanish empires.
These wars fought for independence drained many a nations youth. Toss in the Irish questions for fun. Many English lads were from industrial families, hardworking but not getting the recognition .
The soviets were rebuilding, going to space, first after first.. yet the west was ignoring them and talking double standards. Cuba for instance.
Now let's toss nukes on top of things , during this time frame it looked quite possible that we would just blow ourselves up. Great for moral huh....
The counter culture had nothing to do with Nuremberg sorry again. Its just no.
World war 2 put the nail on the old ways ...with Korea, the cold war and Vietnam finally castrating it and leaving it in the dust.
People didn't want to return to 1938
