All the talk now is of how we might defend ourselves without the US. But almost everyone with a voice in public life appears to be avoiding a much bigger and more troubling question: how we might defend ourselves against the US.

As Keir Starmer visits the orange emperor’s court in Washington, let’s first consider the possibilities. I can’t comment on their likelihood, and I fervently hope that people with more knowledge and power than me are gaming them. One is that Donald Trump will not only clear the path for Vladimir Putin in Ukraine, but will actively assist him.

Now consider our vulnerabilities. Through the “Five Eyes” partnership, the UK automatically shares signals intelligence, human intelligence and defence intelligence with the US government. Edward Snowden’s revelations showed that the US, with the agreement of our government, conducts wholesale espionage on innocent UK citizens. The two governments, with other western nations, run a wide range of joint intelligence programmes, such as Prism, Echelon, Tempora and XKeyscore. The US National Security Agency (NSA) uses the UK agency GCHQ as a subcontractor.
