This is the most known era to us, American educated school kids, because this is the era that the US got to show off its muscles and show that it could bomb anything that it wanted to into oblivion. Just in a span of 30 years, the world saw 2 major world wars, 100 million people dead just from fighting, a disastrous global depression, the invention of WMDs, and a very close and real nuclear winter. But even though all this happened, countries still came together in times of trouble, made arguably the largest strides in rights, equality, science, and technology, and saw many former colonies finally become self sufficient countries. This was also the period in time where we got to see something never seen before in history, something that shook the very foundations of what it meant to be a country and the ruler of one- the inauguration of a meme.
