India, Pakistan and even tiny Sri Lanka have all ignored U.S. concerns, and have hosted Iranian President Mahmoud Ahmadinejad over the past two days. It is a fleeting visit with less than five hours scheduled in Delhi, but it seems like a carefully calibrated piece of diplomacy tiptoeing around the elephant in the room.
 
For, as relations go, India and Pakistan have become bound up with the United States in ways that would have been unthinkable not very long ago. Islamabad is a frontline ally in Washington’s war on al Qaeda and the Taliban, India a growing strategic partner with whom it is pushing a far-reaching civilian nuclear deal that gives it de facto recognition as a nuclear state.
