Kind of defeats the market for your product though. Assuming the US govt is going to stay non-rogue for the lifetime of the product you are buying to defend yourself against all threats, might be a tough call.
In fairness if the US went totally rogue their are few nations they couldn't wreck in short order outside of the ones with a credible ballistic missile program and nuclear warheads.
In that hypothetical no-one wins.
I'm sure there is an obscure plan for that somewhere in say the UK MoD filing cabinets.
I know the US war gamed invading Canada as both a training exercise and contingency plan.
Hopefully they've updated the obscure plan in the years since they gave away the entire carrier air fleet to the US marines, and ordered US F-35s to replace them.
Assuming competence in the halls of the MoD these days seems to be naive.
