>An emotive analogy that once again betrays no understand of trade relation of international politics.

No it's an excellent analogy. The US and Europe relationship works because we agree more often than we don't, and we get more stuff done than we would if we had constant knives in each other backs. But that doesn't mean that if the US can get an advantage over Europe, it will refrain from doing so out of respect.

>You are likely thinking of the Peierls calculations the UK gave to the US in
1940 as part of the Tizard mission, but then the UK went its own way
for several years not realising the sheer scale of what the US was
doing.

I'm also talking about the joint funding, the procuration of Uranium, the design and construction of gaseous diffusion plants, etc etc. It wasn't an equal involvement, but the US violated the Quebec agreement because it suited it.
The point I am making here is that the US dealt in bad faith because it had the advantage.

>The US has been flying European astronauts since Ulf Merbold in 83. Europe does not have its own because it wont pay for it.

The US didn't fly them for free. And lest we forget the interlude between 2011 and 2020 where the US was reliant on Soyuz "Because the US wouldn't pay for it". Stones and glass houses.

>you think you are an expert.

Who claimed I was an expert? Do I need to be to have an opinion?
