The solution to 9/11 was simple, easy, and immediate - seal the borders, implement travel ban and extreme vetting with anyone from the mid-east.
Instead, Bush, Cheney, Blair and the deep state decided to involve ourselves with super-costly, divisive and failed wars in the mideast.
And start the road to the Police State, with the Homeland Security Act.
Combined with a crash program to make America energy independent with drilling and next gen nuclear plants. Imagine if all that money wasted in the Middle East had been spent on energy infrastructure.
