The diplomatic and military surge into South-Central Asia that will define the Obama administration’s early years has already begun. Joint Chiefs of Staff Chairman Adm. Mike Mullen and Centcom head Gen. David Petraeus have become regular visitors to Islamabad and Kabul. Vice President Joe Biden recently came through for huddled conversations, and veteran Balkan negotiator Richard Holbrooke has just embarked on his first trip as special envoy to the region. Enough congressional delegations are passing through that the Pakistani media jokes that there must a “two-for-one” sale on Pakistan International Airlines. But perhaps people in Congress should be looking into ticket prices on China Air and IranAir as well.
