What we have here is a super power never before seen in human history with an unlimited purchasing power and strongest technology around.
Unlimited purchasing power? Lets see what the Chinese have to say about that as they are the US's biggest lender, oh yeah ,that's right, they don't think the US will be able to pay their debts. the more money the FED invents out of thin air, the less it is worth.
In fact, most of the "money" in the US exists solely as binary code, there is no physical "money" to back it up, which is half of the problem with the world economy, and the reason so many countries are moving away from the green back. Which countries? Well, you can start with the list provided by the op, then turn on the news, whatever country is being demonized is probably on that list too.
strongest technology around? you mean all that technology built by china? that's right. That's why the department of defense is on a mad rush to replace every single silicon chip in any military or defense equipment. Because they outsourced production to China, and no one in the US has the knowledge or ability to verify there is no security hole built in.
