in 1945 most of the important world was literally in ruins, except America. We took over. We rebuilt the world. Since then America has only become stronger.

Economically we have forced our policies on most of the developing world (think the Washington Consensus), making it easier for our corporations to control them and exploit their resources. It has lead the US to have by far the largest and most powerful economy ever imagined by humans.

Culturally the US has shaped the aspirations of people all around the globe. Not just with our movies or music, but we have shaped the very frame work that billions of people see the world from.

Politically, look where the UN is at. We have set up puppet states all across the world. We have spread democracy and freedom to countries that didn't even know they wanted it.

Militarily, we still have the best most powerful army on Earth. We can kill people in Pakistan from a room in Nevada via drone.

Educationally, we have the best university system in the world. We attract the best and brightest from all across the world.

Scientifically, we made the internet, we landed on the fucking moon. WE LANDED ON THE FUCKING MOON.

The point of this topic is that, even if America is experiencing a demise, even if China rises, no civilization will ever be as powerful as America was during the later half of the 20th century. If you are an American you literally wont the birth lottery to be born here during these times.
