Sure! it’s a question of how we decide to govern ourselves as a collection of societies.

In a nutshell, I’d recommend a commune made up of federated communes, with decision making done at directly democratic assemblies at the most local level, then sending delegates (who have no power of their own and who can be instantly fired/replaced) to meet with other assemblies to make agreements, in steps going up to the broadest level (citywide, regional, etc) necessary for the decision to be made.
