Per alliance, all democratic nations in the DAPP are REQUIRED to help those being attacked in the west indies.
Canada starts readying its naval forces whom were patrolling southern-US waters and the US bases in the Keys should be the first ones to launch air assaults.
All DAPP nations not near the Cuban location can have a waiting time to attack or support financially. Any DAPP nation who refuses to help in the assault may be forcefully suspended/expelled from the alliance, unless reason can be accepted by America, Canada, or Sweden (essentially the council countries).
Actually, we can try to do peace talks c:.
Also would that airliner thingy technically be upheld by the UN? Also, I don't see how a service can be cheap and have a high payrate without pulling money out of someone's pockets.
