Are we really any more secure now? Also remember Bush invaded Iraq because ...? We’ve lost how many lives from all these adventures and what do we have to show for it? Republicans and Demo-rats are two sides of the same coin with both of them pushing us towards some corrupt oligarchy police state. Freedom? What is that in Amerika?
The US had two very important, STRATEGIC national interests in Iraq...one of which even the pacifist Jimmy Carter was abe to discern and articulate with the Carter Doctrine: Oil must flow from the Persian Gulf to open markets and the US is willing to engage in existential war to ensure it does.
And the second was to ensure a crazy dictatorship did not maintain a stockpile of WMD that could be distributed to America's enemies. Alas, we failed to acquire those weapons and they probably went to Syria and then to ISIS.
But the motive was correct.
