Saddam had every home in Iraq armed with an assault rifle.
The fall of the U.S. will be economic and the invasion will be ushered in by right-wing forces in America who will open the doors to a foreign invader rather than sit back and watch the working class take state power.
In every country that has ever been under the thumb of an imperialist power, that imperialist power ALWAYS, without exception, props up a hated, murderous, treasonous, RIGHT-WING dictator whose job is to allow his own nation's people to be raped and his country's natural resources to be looted by the imperialist power and its allies. Frequently, the imperialist power conspired to overthrow a leftist government or a nationalist government whose people were living a higher standard of living through the exploitation of their own nation's resources.
The right-wing in the U.S. is responsible for off-shoring our better-paying jobs, attacking striking workers, slashing wages and benefits, looting trillions from the public till for bankster bailouts and imperialist wars, driving down the value of the dollar, buying politicians, stealing elections, assassinating leftist political leaders, attacking us on 9/11, etc.
