Indeed, and trusting the US to protect allies from invasion was a bad call. The leap from "perhaps US allies should up their defense spending to what it should have been all along, plus a temporary bonus to catch-up/modernize" to "pre-emptive attack and iron-domes for everyone should be on the table" is both eroneous and wasteful.

Don't encourage countries to bankrupt themselves buying solutions that are sold mostly by the US - thats exacly what my government would love best to enrich defense contractors and justify continued record spending, plus more meddling, I promise.

"Treat x as an attack that requires immediate action, you can't afford to make rational long-term decisions today" is the hook-line-and-sinker CIA/fascist narrative, always has been.
