If you're a serious grownup in the VSG administration, you have to know how to persuade him

The word "oil" came across his radar screen and that was the selling point:

President Trump was persuaded to leave at least several hundred troops behind in Syria only when he was told that his decision to pull them out would risk control of oil fields in the country’s east, according to U.S. officials.

Trump had rejected arguments that withdrawing U.S. forces would benefit American adversaries, while endangering civilians and Kurdish allies, but he tweeted Thursday that “we will NEVER let a reconstituted ISIS have those fields.”

Defense Secretary Mark T. Esper confirmed on Friday that troops would remain in eastern Syria to prevent the oil fields from being retaken by the Islamic State.

Speaking at NATO headquarters in Brussels, Esper said that military planners were “considering how we might reposition forces in the areas” and that the deployment “would include some mechanized forces” such as tanks or other armored vehicles and support personnel.

A U.S. official with knowledge of operations in Syria said that Trump’s interest in the oil provided an opportunity for the Pentagon, which was unhappy with the initial decision, to temper his insistence on a full withdrawal and allow counterterrorism operations and airspace control to continue.

“This is like feeding a baby its medicine in yogurt or applesauce,” said the official, one of several who spoke on the condition of anonymity about internal U.S. deliberations. 

Now, what would be the angle for getting him to sign off on actual consistent, productive courses of action on North Korea, the deficit and health care?
