I really did. I am now going to massively oversimplify the popularly believed geopolitical situation over my life by decade. As with any oversimplification, it is not meant to be 100% correct, but the basic outline is correct.
1970's = We lost Vietnam, and worried we might lose everything. The supposed dominos were falling in the wrong direction.
1980's = There was no way the Cold War would ever end. The Berlin Wall was forever. We could only hope for lessoning tensions, but on the other hand Reagan told us that war was inevitable.
1990's = We won. Russia and China were going to become more and more like the USA. It was the end of history. Poland and the Baltic States joined the EU, and NATO. It was only a matter of time before Russia joined both.
2000's = We lost. Al Qaeda could strike us in our homeland. It was far closer to home than Pearl Harbor. It was more like something that happened in the War of 1812. In response, Bush invaded Iraq, which meant we were unable to do much anywhere else for a decade.
2010's = We were still hoping for the best from Russia, but being disappointed. We were still hoping for the best from China, but being disappointed.
2020's = The book is still being written on that. We were at first sure that the major conflict would be with China, but so far it has been with Russia.
