Also, I'm generally bothered by comments like this one that stir up the general human tendency toward xenophobia. We should be fighting that tendency within ourselves, not fighting the out group. Whichever group of people we want to demonize, we should remember that they're people just like us. We shouldn't punish the majority of them for what a minority are doing to us.
If you run a small-medium sized business in the US blocking all of countries you can't do business with anyway will save a ton of trouble.
My reasoning for these kinds of stats is usually: Of course it makes sense to attack targets in jurisdictions which can't catch you or equally hide in a country which won't extradite you. (But I never looked into it to any depth, so it's baseless reasoning.)
