Hence why Canada is now considering bailing on its purchase of F-35s.
The prospect of getting cut off is hardly theoretical: the US already partially halted support for Ukraine's F-16s (I'm not sure where this stands at this precise moment).
The US is clearly demonstrating it is an unreliable partner in defence. Western nations cannot buy into a platform when its supplier might go from being a democratic part of the West to aligning with dictators and autocrats literally overnight. This doesn't just mean that platforms like F-35 are vastly less desirable to Western militaries, it also means that other things we thought we could rely upon, like the nuclear umbrella, are also unreliable, which is likely to lead to nuclear proliferation.
