Yep. Kept Communism from spreading West while it was in place. Since it came down, German politics and society have swerved decidedly to the left. Meanwhile Germany's standard of living is declining relative to the rest of the world. The wall coming down has greatly benefited former East Germany, but it's been a boondoggle to former West Germany, which has been forced to cope with Soviet-era social problems.
You somehow view violent fascism as merely 'quaint', or 'backwards'? We should thank God that these nations don't currently posess enough technology to pose a threat to us. If they did, we'd all be dead or Dhimmi. Giving them wealth and technology without first effecting the destruction of their fascist views is just baiting trouble.
"Quaint?" Uh...no.
Kept Communism from spreading West while it was in place.
The problems in Germany exemplified by the Berlin Wall...good because they kept W. Germany from being infected? Never heard that one before.

Exactly right. This goes to show you that America didn't solve all Germany's problems in a fell swoop. Neither will Afganistan's problems be solved quickly. Particularly since they are more backward than Germany was.
