As in the 60s and 70s?
Bay of Pigs
JFK Assasination
MLK Assasination
RFK Assasination
Vietnam war lossses, losing battles, lies, all that ugly stuff.......Cambodia bombings, napalm, agent orange, do we really need too look back at all that shit?
Juntas and interventions by CIA in foreign countries, overthrowing legitimate governments, etc.
Nixon resignation for being a crook.
Where to begin, and where to end?
America’s future was changed radically.
The two other things, which were great, that stand out during that time are the walk on the moon, and Woodstock, music.
