Shouldnt Americans be ashamed of defending actions like attacking 2 countries that had nothing to do with 9/11?

No shame here, Iraq and Afghanistan those were fixer uppers anyway. We did them a favor at great cost to ourselves by invading. The Invasion of Iraq was unnecessary but after the fact it has great potential to a positive force for progress in the world. However trying to nation build in Afghanistan maybe an unrealistic goal. We will eventually get to Saudi Arabia but as of now they are allies and not a nuclear threat. Iran, Pakistan, North Korea are of much more concern.
