Welcome to the world in 10 in an increasingly uncertain world.
This is the Times daily podcast dedicated to global security today with me,
Tom Noonan and Alex Dibble.
Europe's long been reliant on the US for its defence in terms of troop numbers,
intelligence and hardware.
But as NATO allies try to rearm in response to Donald Trump's threats,
German media's discovered Germany's advanced F35 jets could be grounded against its will,
not by its enemies, but by the United States.
Given a number of America's allies have bought the jets,
how seriously could this hamstring Europe's attempts to defend itself against Russia or any other enemy in future
if the relationship with the US doesn't improve?
And is there anything Europe can do about it?
Our guest today is the Times Berlin correspondent Oliver Moody.
Oliver, just talk us through how the US would stop F35s flying,
because it's not as though there's a kill switch, is there?
And planes are just going to drop out of the sky suddenly.
What we are talking about here is two slightly different things,
the first of which is this deep suspicion among many of the European allies that have bought the F35 or ordered it,
that the US doesn't need a kill switch,
that it can simply cut off the spare parts and the software updates to the F35s,
