The Russian submarine is on the fritz and as such remains at the bottom of the North Sea. Its fancy nuclear missile, meanwhile, has been purloined by the Americans in an operation presumably entitled Let’s Flush Our Alliance With the Brits Down the Bog (and potentially instigate the third word war while we’re at it). The prime minister, Nicol Trowbridge (Rory Kinnear), remains oblivious and a berk. The Russians are similarly unaware of the theft, for now at least, but the US ambassador to the UK, Kate Wyler (Keri Russell), predicts the eventual discovery will blast the Kremlin’s ushankas skywards. “Russia will come to get their sub,” she warns her unblinking husband – and current US vice president – Hal (Rufus Sewell). “They will lose their shit when they find their apocalypse weapon is gone and they will attack the United Kingdom!” “Hmm,” replies Hal, who has, one suspects, shiftier fish to fry. “Mmm.”
This is where we find ourselves as The Diplomat returns for a fourth series of exquisitely fraught geopolitical skulduggery. Which is to say; we’re stuffed. Poised on the precipice of Big War, a situation almost wholly attributable to the whims of the US president, Grace Penn (Allison Janney). Yikes. But also, in a very real sense, woohoo. Because there are few things as entertaining as The Diplomat in a bad mood, even if the stress induced by its doomsday theatrics requires much diaphragmatic breathing and the odd diplomatic sprint to the loo.
