What if Aliens from Mars invaded America? Would they use drones to control us? Monitor our cell phones? Wear body armor when patrolling our streets? Cover their eyes with protective glasses? Live in isolated compounds? Move in convoys? Would they look so out of place that we could spot them no matter how hard they tried to camouflage themselves?

So why when we invade another country do we expect to be welcomed?

Stop playing Space Invaders and just cut 'defense' spending to defense levels!
