The ghosts of the Obama era haunt the White House once more. But this time, it's not a policy debate. It's a fracture in the transatlantic alliance.
Downing Street has quietly allowed the Iran nuclear deal to breathe again. Not with fanfare. But with a series of backchannel moves that have left Washington scrambling.
What happened? The Joint Comprehensive Plan of Action, or JCPOA, was Obama's signature foreign policy achievement. Trump tore it up in 2018, calling it 'the worst deal ever'. Now, Britain is effectively resuscitating it, piece by piece.
It started last month. A British diplomat in Vienna reopened a dormant channel with Iranian counterparts. No press release. No announcement. Just a quiet re-engagement on nuclear inspections. Tehran responded with a temporary halt to enrichment at a disputed facility. A confidence-building measure, they called it.
Then came the leaks. A memo from the Foreign Office to Number 10, seen by this bureau, concludes that the JCPOA 'remains the most effective mechanism to prevent a nuclear-armed Iran'. The language is deliberately anodyne. But the intent is clear: Britain is going it alone.
Why now? Three reasons. First, the White House is consumed with domestic turmoil. Trump's impeachment trial and the looming election have paralysed foreign policy. Second, the EU has signalled it wants to salvage the deal, but lacks the political will. Britain, post-Brexit, sees a chance to lead. Third, the intelligence. A classified assessment shared with allies warns that Iran is within six months of a breakout capability. Not a bomb, but the capacity to build one quickly.
Where does this leave the special relationship? In a cold place. Trump's national security advisor called the British move 'counterproductive' in a phone call with his counterpart. But the British response was blunt: 'We disagree'. The official line is that Britain is acting in its own national security interest. The subtext is that the White House is unreliable.
What about the Labour opposition? Jeremy Corbyn has praised the move, but that endorsement is a poison chalice. The party is split on Iran. The shadow foreign secretary backs the deal, but many Labour MPs from constituencies with strong Jewish communities are deeply sceptical.
The real battleground is within the Conservative party. The 1922 Committee has received letters from backbenchers demanding a Commons statement. The Prime Minister's position is delicate. He was a vocal critic of the JCPOA in the 2016 EU referendum campaign. Now he is embracing it. Insiders say he has been persuaded by the intelligence community. But his 'never apologise' stance means he will never admit a change of heart.
What comes next? Expect more shuffling, not drama. The British strategy is to build a coalition of the willing: France, Germany, and possibly China. Russia is a wild card, but Kremlin watchers say Putin will not miss a chance to embarrass the US.
The stakes are high. If this works, Britain reclaims a role as a global diplomatic player. If it fails, the fallout will be radioactive. Literally, in a worst-case scenario.
One senior diplomat told me last night: 'This is a three-dimensional chess game. The Americans are playing checkers.' That sums up the mood in Whitehall. Quiet confidence. But also a recognition that there are no clean hands in this game.
The question is whether the gamble pays off. Or whether, as Trump would say, we have 'made a terrible deal'.
For now, the advantage lies with London. But in politics, as in diplomacy, the pendulum swings fast. Watch the room. Watch the polls. And watch Tehran.
