you live with, and/or are supported financially by your "well off" parents. Or you might still be in school hustling on loans and part time jobs. regardless, you have little perspective on how bad the world economy is right now. And the US is by no means over the hump in regards to the recession...
China is starting to exert their military influence in the eastern pacific, and are starting to develop a miltary that can compete on the same field as the US and Russia. And China has been fucking with US allies lately, and we have had a couple diplomatic run-ins with them lately, so war is a remote but very real possibility.
Not to mention that a nuclear Pakistan FUCKING HATES america, and top ranking military officials are buddy-buddy with al queda.
