Which country do you think is the most serious geopolitical and military rival of U.S. and who will be in 20 or more years? Which country should be the main concern of U.S. strategic institutions?

The US. History shows that a lot of powerful empires break down from the inside. If we're talking about outside threats then obviously China, Russia (on smaller scale) maybe Iran.

Main rival to US? Ignorance, groupthink, and an archaic desire for simplistic solutions to often complex and nuanced issues.

Bomb Conservativia!

The good 'ol USA is its biggest threat to itself. Corporate short term profit will crumble the American culture over the next few decades.
