Examine Peace Corps programs and consider the benefit and cost ratio. Concentrate on those countries that offer economic and political advantages for the U.S. Better yet, spend that money on the disadvantaged at home.
I think we should defund the Peace Corps and use the savings to fund an organization that uses volunteers to assist hard-working folk in third world countries by providing educational, scientific and agricultural support.
On occassion a political or natural event requires immediate response. Organizing reserve units that can deploy for immediate need may be able to accomplish more than unifirmed military personel could.
