In the next 100 years I rekon that The Middle East will finally join forces and rise up against America, China will become the next economic if not military super power shifting the pressure on Russain borders, Russia will be forced into securing its reserves of oil forcing Europe to secure its own borders against the rising Red Army, defenses will go up across the planet and the world will descend into a recession so great the popluation will not recover from it even if they manage to survive the pending environmental disaster.
Mark my words, it will all end in tears.
