The U.S. policy in Afghanistan under President Obama is changing, and will likely mean a ramped-up effort with more troops. Does Afghanistan risk being another quagmire, with U.S. troops occupying the country for years? Or will a “surge” there work? What is the

measure for success in Afghanistan? What role should neighboring countries play? When will U.S. troops come home for good?
