Please read my U.S. Cannot Force Regime Change in Pakistan . Also for those who are so, so surprised at what's happening there, check-out my policy paper Pakistan in America's War against Terrorism: Strategic Ally or Unreliable Client? (from 2002)and the two commentaries The Real War on Terrorism Is in Pakistan, Not Iraq (2003) and If Iraq, Iran, and North Korea Are the "Axis of Evil," Why Is Pakistan an Ally? (from before the Iraq War), as well as my op-ed in the Los Angeles Times Outsourcing the Hunt for Bin Laden.
