Word from Whitehall is that the nascent US-Iran accord has sent tremors through Beirut and Tel Aviv. This is not a done deal. It is a live wire. And Downing Street is carefully weighing its grip.
The deal, as leaked from Washington, offers Tehran sanctions relief in exchange for nuclear curbs. Fine. But the fallout? That is where it gets interesting.
Lebanon first. Hezbollah, Iran's proxy, sees this as a lifeline. More cash, more arms. The fragile Lebanese state? A bystander. Expect the Shia militia to tighten its stranglehold. The UK has troops in UNIFIL. Their safety just got dicier.
Now Israel. Netanyahu is fuming. He sees a nuclear Iran with a green light. His recent courtship of normalisation with Saudi Arabia? Now on ice. The UK, a close ally, must manage Israeli rage while not scuppering Biden's grand bargain.
Where does Britain stand? We are the bridge. Our diplomats are shuttling. Expect a quiet push for a 'sunset clause' in any deal. We want limits on Iranian missiles and support for proxies. The US needs our intelligence and our voice in Europe.
Backbenchers are restless. The usual suspects calling for a harder line. But the PM knows the reality: Britain has no seat at the table in Vienna. We influence via Washington and Brussels. So expect careful footwork, not grand gestures.
The keyword here is 'contingency'. The FCDO is gaming out scenarios. A Hezbollah rocket barrage into Israel? A Saudi break with Washington? Britain's role as a stabiliser is being tested. Watch the Palmerstonian phrases emerge from the Foreign Secretary.
In the lobby, the chatter is about 'managing expectations.' The deal is likely. But its implementation is where the cracks show. Britain will be the quiet voice in the ear, ensuring our partners are not left exposed.
The Middle East is a chessboard. This deal is a new queen on the board. Britain? We are the player who has seen this gambit before.
