The European Union is encircled on the outside, split three ways on the inside, and is saddled with a corrosive currency union that is still not established on workable foundations and is likely to lurch from crisis to crisis until patience is exhausted.

Europe’s economic “Lost Decade”, and the strategic consequences that stem partly from this failure, have emboldened enemies and turned the Continent into a dangerous neighbourhood. The EU now badly needs a friend on its Atlantic flank.

While it would be undignified for any British government to exploit these circumstances (and Theresa May is certainly not doing so) this is the diplomatic and military reality as Britain triggers Article 50.

Along an expanding arc across the East, the EU faces a pact of autocrats. Russia and Turkey are moving closer to an outright alliance - an ideological hybrid like Molotov-Ribbentrop - that cuts at the heart of Nato. Both are openly at war with the post-Second World War liberal order.

The Kremlin is meddling in the Baltics, the Balkans, and the EU’s internal democracies. Vladimir Putin acquired a military edge during the energy boom - when the EU was disarming to meet austerity targets - and now enjoys a window of opportunity to extract maximum advantage.

In the West, the EU faces Donald Trump. This is a US president who refused to shake the hand of German Chancellor Angela Merkel. For the first time since the launch of the European project in the 1950s, the US no longer sees the EU as an asset in the diplomatic equation. Many in the White House would happily see it broken up.
