Electromagnetic catapults are a “least concern” technology I would say, but that aside, currently our defence industries are intertwined. Thinking the EU is fully dependent on the US is delusional.

People are about to find out that even when the US often leads the way, there are also EU companies critical to US weapon systems.

Sure, you can “DIY” everything, but massively altering your supply chain is rarely a good idea. Will Orangeman realise that? We will see.
