Absolutely. Canada is almost certainly going to cancel or severely limit a pending F35 order, and is actively sourcing aircraft and negotiating mutual arms deals with European partners.

… which is hard to do for European plane makers that have engines with parts licensed from US companies.

Hopefully this all leads to more countries stopping relying on US trade.

Of course, NATO was founded on the assumption that the US is a reliable trading and security partner, and the defense supply chains reflect that assumption. It will take time to untangle those chains, but you're watching all of NATO speed-running that process right now.

I'm sure Rolls Royce expects their order book to grow over the next few decades. Likely some engineers have been tasked with researching the viability of creating drop-in replacement models for American engines.

Well. They had it once. Maybe they could resurrect and modernize it :)
