As Barack Obama heads into his second hundred days in office, let's head for the big picture ourselves, the ultimate global plot line, the tumultuous rush towards a new, polycentric world order. In its first hundred days, the Obama presidency introduced us to a brand new acronym, OCO for Overseas Contingency Operations, formerly known as GWOT (as in Global War on Terror). Use either name, or anything else you want, and what you're really talking about is what's happening on the immense energy battlefield that extends from Iran to the Pacific Ocean. It's there that the Liquid War for the control of Eurasia takes place.

Yep, it all comes down to black gold and "blue gold" (natural gas), hydrocarbon wealth beyond compare, and so it's time to trek back to that ever-flowing wonderland -- Pipelineistan. It's time to dust off the acronyms, especially the SCO or Shanghai Cooperative Organization, the Asian response to NATO, and learn a few new ones like IPI and TAPI. Above all, it's time to check out the most recent moves on the giant chessboard of Eurasia, where Washington wants to be a crucial, if not dominant, player.

We've already seen Pipelineistan wars in Kosovo and Georgia, and we've followed Washington's favorite pipeline, the BTC, which was supposed to tilt the flow of energy westward, sending oil coursing past both Iran and Russia. Things didn't quite turn out that way, but we've got to move on, the New Great Game never stops. Now, it's time to grasp just what the Asian Energy Security Grid is all about, visit a surreal natural gas republic, and understand why that Grid is so deeply implicated in the Af-Pak war.
