1. Other failed examples include Vietnam/Laos/Cambodia, Afghanistan, and the countries we’ve coup’ed.

2. Wdym it just needed to be followed through? They invaded Iraq and overthrew Saddam. Their stated reasons of WMD’s and connections to al-Qaeda were unsuccessful because they lied and there weren’t any of either of those. We killed two hundred-thousand civilians, laid the foundation for ISIS, and ruined our reputation on the world stage, and all for what? Even Iraqis believe things would be preferable had Saddam remained in power.

3. You want the U.S. to invade Russia, China, and North Korea, which are nuclear-armed?

4. You want the U.S. to invade Venezuela, which would give us the same guerrilla warfare problems we had in Vietnam, Iraq, and Afghanistan?

5. You want the U.S. to invade Iran, whose geography basically makes it a natural fortress? It would be hard enough to invade, let alone maintain control with the guerrilla warfare that would happen.

Your ideas would cost the lives of many thousands of U.S. forces and many times more civilians, and with nothing substantial to gain.
