The political and organizational de-federalization of the U.S. is already well underway and we are really just starting to see the preliminary military conflicts with things like Trump actively threatening Chicago.

If this leads to actual Balkanization has more to do with if the regions have strong identification with each other and themselves more than the federal government, which given how destabilized people’s identities are due to the internet is unlikely to manifest in that way. On the other hand, intense regionalization may occur as a reaction to internet generalization. For example, I have seen more people joke about Wisconsin retaking the Upper Peninsula of Michigan than ever before in the last couple of years, and quite often todays jokes are tomorrows policies.
