> You can't simultaneously argue that NATO is a "protection racket" for the US to sell weapons and control European foreign policy, and also argue that the EU would be in trouble without the current levels of US participation.
Sure I can. I can both deny you the means to defend yourself, forcing you to rely on me for protection. That's the definition of a protection racket.
> The US has spent 3-4% of GDP on defense for decades ...
Ah, now I get it. This is Trump administration talking points eg [1]. Those talking points are just a shakedown for American defense contractors. Again, just like a protection racket. Because it is a protection racket.
> Most of America's allies would not be able to fund their generous social programs
This is revisionist history at best. The US has done their best to undermine and dismantle European social programs. Even something like the Norwegian sovereign wealth fund was only tolerated because of Norway's strategic position in the North Atlantic as a foil against the USSR.
> During Operation Prosperity Guardian, Houthis started attacking commercial shipping vessels in the Red Sea, directly threatening European trade routes,
America was protecting Israel's trade routes. Let's be clear. European trade routes largely just rerouted around the Cape of Good Hope.
But again we come back to the protection racket. You can't both have a protection racket (and, by extension, defang the militaries of the protectorates) AND expect military help, particularly when the entire thing only happened because of the US material support to Israel's genocide.
> With Operation Epic Fury ...
Operation Epstein Fury FTFY
> ... the US asked to use jointly operated bases for staging,
Yes, literally nobody wanted the US and Israel to launch an unnecessary, unprovoked and ill-planned war on Iran other than the US and Israel. Everybody else, including Europe and other Middle East neighbours, all of whom are American client states, basically, begged the US not to do it. And they did anyway.
So yeah, you're on your own.
> Can we actually be clear on "reliability"? There is not a single defense analyst in the world who seriously believes the US wouldn't IMMEDIATELY defend Canada if Russia launched an offense against them.
Not a single defense analyst would even seriously consider such a prospect any more than Fiji invading the Central African Republic. What are you talking about?
