With $100 billion being spent every year in Afghanistan, why are we there? In fact, why are we fighting anywhere? What has been accomplished in Afghanistan in the last 10 years? $1.2 trillion would have been better spent on defending our borders and the military. The money would have stayed in the US, boosted employment and helped to boost the economy. Of course, a lot of people would still be alive, suffering would be eliminated and trillions would not be needed for medical treatment and rehabilitation.
How can $100 billion per year cost the US trillions of dollars per year? The side benefits of a strong border defense are limitless and would save trillions more. A few of the very many benefits, other than preventing the importation of nuclear weapons or other weapons of mass destruction, include substantial reduction of transportation of illegal drugs; transportation of counterfeit goods across our borders; and transportation of unwanted animal life. Illegal drugs alone probably cost the US economy trillions of dollars. Counterfeit goods costs US jobs and loss of tax revenue. Unwanted foreign animal life is already threatening millions of dollars of damage to the US food supply.
Saving trillions more which was and is spent on other wars and continue to be spent in other countries (even South America), our defense will be stronger than ever, taxes will be reduced and the national debt will be eliminated.
