OUR REPUBLICAN PRESIDENT:

[W]hy are thousands of Americans in Erbil these days? It is not to take in clean mountain air.

ExxonMobil and Chevron are among the many oil and gas firms large and small drilling in Kurdistan under contracts that compensate the companies for their political risk-taking with unusually favorable terms. (Chevron said last week that it is pulling some expatriates out of Kurdistan; ExxonMobil declined to comment.) With those oil giants have come the usual contractors, the oilfield service companies, the accountants, the construction firms, the trucking firms, and, at the bottom of the economic chain, diverse entrepreneurs digging for a score.

Scroll the online roster of Erbil's Chamber of Commerce for the askew poetry of a boom town's small businesses: Dream Kitchen, Live Dream, Pure Gold, Events Gala, Emotion, and where I, personally, might consider a last meal if trapped in an ISIS onslaught, "Famous Cheeses Teak."

It's not about oil. After you've written that on the blackboard five hundred times, watch Rachel Maddow's documentary "Why We Did It" for a highly sophisticated yet pointed journalistic take on how the world oil economy has figured from the start as a silent partner in the Iraq fiasco.
