DailyMail: Britain must prepare if Trump pulls Support for UK’s Nuclear Trident, Nuclear Deterrent could not be maintained without US Help

DailyMail writes: “Britain must start preparing for the ‘terrifying’ possibility Donald Trump may pull US support for the UK’s nuclear deterrent, experts have warned.

The UK has its own nuclear warheads but fits them to American-made and maintained Trident ballistic missiles carried in the Royal Navy’s Vanguard Class submarines.”
It is a subject never discussed in public: how does Britains nuclear arsenal work.
It appears that it is heavily dependent on US technical support and maintainance.
The Trident missiles are US made and delivered at demand to the UK. The nuclear warhead, in line with non-proliferation duties are “made in the UK”. UK’s nuclear weapons are sea-based, on submarines.
France is an autonomous nuclear power, unlike the UK which depends on the US Trident missiles. France’s nuclear arms are all made in France. They are sea and air-based, with warheads, missiles, submarines and planes “made in France”. As such, France is the only true independent nuclear power in Europe, besides, of course Russia which has the the World’s largest nuclear arsenal (home made).
A serious US-UK dispute may create the risk that the UK nuclear deterrent is jeopardized.
