This checks out. Just look around. Large players attacking large players is the norm with smaller nations being left out of it.

Obvious exceptions. Israel, which is effectively a wing of the US government in these terms so also large. Iran / Palestine but these are really acting as part of the larger Muslim community and not as true individuals.

There is the risk of remaining large collectives attacking the small agoras. This is solved by the fact that a proper agora would be able to quickly dissolve while the members move to other agoras. Remember, free association with no coercive lock in. That dissolving removes many of the rewards for attacking.

Even if dissolving the target fails, the scale of human suffering was reduced by shrinking the size of the target population.
