Smarter networking people of reddit, i have a geo-ip question

Hey,

My macro knowledge of how the Internet works is admittedly limited to the basics, but I understand VPN services, basic layers of networking, and the like. My questions is this:

With all the drama certain countries cause for our Internet and governments in the West in general, why is geo-ip filtering not a commonly deployed tactic of anti-cyber warfare to the extent that we could macro block entire countries in the same way lots of businesses currently do? Is this tactic already employed on a large scale in gov orgs? The diplomatic situation behind this kind of thing aside, could it be done feasibly on an ISP scale? Would it break everything? Do we depend on a country like Russia or Eastern European countries for some services we couldn't live without?

This question is purely academic please don't bring politics into it, thank you.
