#2 If the best they can get for their USSR and all of Eastern Europe is South Africa and Zimbabwe... well, they ain't on the top three list of totalitarian global menaces anymore.

You've got to be kidding me, if you think we should divert an ounce of resources from fighting Islam to dealing with a defunct ideology. Socialism "jumped the shark", so to speak, even the Chinese are mapping their way out of it.
Zimbabwe is not socialist. It is a dictatorship. And nothing that happens there is particularly important to us here.
South Africa voted for the mess its got, now it's got to lie in the bed it made.
If you're really worried about a return of socialism, then the EU should be your focus, not marginal third-world countries.
In the meantime the rest of us will be fighting the jihadis, and would be pleased to have you join us.
