US allies (no need for the scare quotes, unless you think allies are vassals..) would definitely help out the US. Granted, I'd hope you cutting your military a blank cheque would mean it'd perform well enough that it wouldn't be a breaking point. You Americans getting to experience a war first hand would be educational, though.
As for saving money leaving Europe, you're joking about defense spending going down, right ?
Aside, what's with people trying to portray 2l3374U as a Putin apologist or on Russia's side here ?
