The Closing of the American Border is a provocative, behind-the-scenes investigation into the consequences of America’s efforts to secure its borders since 9/11. Basing his conclusions on extensive interviews with former secretary of homeland security Tom Ridge, former secretary of state Colin Powell, other Bush administration officials, and many of the innocent people whose lives have been upended by the new border security and visa rules, Edward Alden offers a striking and compelling assessment of the dangers faced by a nation that cuts itself off from the rest of the world.
