Today is AfPak Day at the White House as President Obama hosts the leaders of Afghanistan and Pakistan. It is hoped that the summit will lead to new resolve to combat the Taliban and a new spirit of cooperation at the regional level. I’d like to refer you to this White House blog post in which President Obama announced his new comprehensive strategy for Afghanistan and Pakistan. What is so new about this? President Obama has appointed a regional envoy and made the strategic choice to deal with both countries together rather than as separate and disconnected security problems. It’s all about linkages.
