Nah, not really. The US is still the largest economy, still the largest manufacturer, and our military is the envy of the world. I'm no American exceptionalist or any other bullsh!t like that, but in a straight up non-Iraq/Astan/Vietnam type of war we would make quick work of an enemy in a straight up fight. They can own us all they want, but they can't repossess anything without the repo man coming back in a body bag.
