Neighboring countries that trade and are in each other's supply chains + economic zones don't go to war. See: the US' painful and bizarre attempts at butchering its relationship with Canada. The integration of the two economies means that such ham fisted manoeuvres take money out of people's pockets pretty fast. In a pre-mass travel world, I can see someone like a certain leader attempting to annex Canada. Now? It's unthinkable. Just saying it causes billions in damage.
