I gave the brief summary; it wouldn't be as rapid as I explained. Tin would probably gradually piss nations off one by one, by following through with their threats to shoot down any nation's planes and by impounding foreign ships and impressing their sailors. It'd also take a while for the global economy to start reeling from the sudden closure of an entire market. If Avalia declared war immediately (which might mot even be the case) then it might be a while before other nations get embroiled and start piling in, so you could do whatever while the war remains isolated.

This doesn't have to happen right away, either. How soon this begins and how quickly we bring other nations in can be determined once we choose which conflict to go with.
