You would usually say with total confidence that if anyone can write the manual on how to survive a visit from Donald Trump, it's the Brits. There is no country better at rolling out the red carpet without picking up any stains. No nation has more experience in deploying pomp to dignify an office, honor an alliance or exude unrivaled soft power status, all without giving up too much dignity or altering the course of British policy in the process.

But these aren't normal times. The government of Prime Minister Theresa May is on its way out and 13 candidates are vying to replace her as prime minister, most promising a quickie divorce from the European Union and a bright future of better international trade deals. The country's two main political parties are in disarray and bleeding voter support, while two of the most popular politicians in the land — Conservative front-runner Boris Johnson and Brexit Party founder Nigel Farage — advocate crashing out of the EU with no deal on Oct. 31.

No wonder the Trump deal antennae (or at least those of his chief trade negotiator Robert Lighthizer) are going wild. Britain's top trade allegiance is for sale and its domestic politics are being dramatically realigned. The U.S. president is emotionally attached to the populist, anti-establishment message of Brexit. But his team also senses a bargain and an unmissable opportunity here. The president is promising a "very large trade deal" to whichever leader can deliver Brexit.
