we have to acknowledge that U.S. and coalition efforts to date have, at most, limited success in actually reducing ISIS oil revenues.

There should be no part of ISIS oil enterprise where people feel safe to work.

You commend the military's recent decision to strike, as you said, larger pieces of ISIS oil infrastructure.

I think clearly ISIS is the most serious terrorist threat we face today, and we need to take all practical steps to defeat them.
