A geographic split of Google doesn't make sense. The right thing to do is to take each of the areas where Google is a monopoly and break them out, and prevent the broken up pieces from providing overlapping services (at least for 20/30/50 years).
I would break out at least:
Ad network
Web search
Operating systems
And put everything else in a separate company. That would contain their other consumer services (gmail, finance, docs), whatever g-suite is called now, cloud services (until they shut down), their internet balloons and what not and maybe Waymo.
You can allow the baby-Gs to contract with each other (web search needs an ad network), but require the terms to be public and frand; maybe with some sort of second source requirements.
This doesn't eliminate any of the monopolies, but it eliminates the use of one monopoly to entrench another.
