Secretary of State Mike Pompeo’s most recent announcement on Iran policy has raised some eyebrows. He indicated on Monday morning that the Trump administration will not renew waivers to importers of Iranian crude and that other suppliers (meaning Saudi Arabia) have agreed to increase production in to ensure the global oil market remains well-supplied. Skeptics question whether — after last summer’s debacle — there is sufficient trust between Washington and Riyadh for this arrangement to work. What skeptics may not have digested is that, while timing remains a problem, this is a classic win-win situation. It is a near-perfect example of the very limited universe of occasions when transactional diplomacy could actually work.
