Like it or not; accept it or not; Carmine's is a participant in this war and they must choose a side ... then deal with the challenges of their decision as there will always be challenges however they choose.
But the important thing to bear in mind is that it's their decision to make and no one, in a free society, can make that decision for them.
In a war, far better to spend your energy attacking the general than attacking the person hired to hold his horse.
