CNN already blew a hole in Trump’s ideas for how to fight Daesh, a hole so wide you could drive a BMP through it:

“If I win, I would attack those oil sites that are controlled and owned — they are controlled by ISIS,” Trump said. “I wouldn’t send many troops because you won’t need ‘em by the time I’m done.”

But that strategy might do more harm than good, according to two former U.S. military officers and CNN military analysts who looked at Trump’s suggestion. That’s because bombing Iraq’s oil fields would be a serious blow to Iraq and efforts to recover once ISIS is expelled from the country.

“You’re destroying the infrastructure of Iraq, you’re not really doing much to hurt ISIS,” retired Lt. Col. Rick Francona said. “At some future point those oil fields will have to help regenerate Iraq.”

The United States did strike oil fields in Kuwait during Operation Desert Storm in the 1990s, which hurt Kuwait for years after the war.

While Trump suggested that he would then send in Exxon or another oil company to quickly rebuild the infrastructure once the conflict is over, Francona and Lt. Gen. Mark Hertling, another CNN military analyst, said rebuilding infrastructure is easier said than done — especially when other surrounding infrastructure has been damaged in the process.

“We’ve made some huge mistakes in terms of just bombing things we think can just bring a nation to its knees,” Hertling said. “It’s not the people you’re going against and yet those are the ones you’re going against the most when you’re talking about indiscriminate carpet-bombing.”
