The thing is, if Brazil, Russia, India or China ceased to exist, the world will feel MUCH greater effects than if the US suddenly disappeared. If the US disappeared, people would rise up a heck of a lot of dust over the internet, but eventually(within 2 months), everything the US gives the world predominantly(mainly movies, music and... well, that's it), would be replaced with products from France and the UK. Whereas the BRIC lands are irreplaceable. Even with their problems taken into account(personal freedoms, coverage, economic stability) they will, by the year 2050(very much likely sooner) completely take over the world economics market.BradenK, sure, the world will feel the impact of the disappearance of the US. Briefly. But can you imagine the impact of a Chinese block on all exports? That's a mild effect(compared to revolution, wars, ceasing to exist, etc.), and it's scarry stuff!
Wow, what are you smoking? If America dies, the world losses our technological advancement. Are we not, overall, the most high tech country right now?
Can other countries maintain the technological edge we can? Oh yeah, working in a retarded communist nation where I get paid sh*& farmer wages to work as a high tech scientist while getting beat over stupid crap (i dont know because maybe I pissed standing up instead of sitting down?) is real good incentive to devote 20 hours a day to advancing my country.
