I think you really need to understand vietnam before you make the stupid assumption the big bad super power USA lost to vietnamese farmers.
The U.S. also had a higher kill ratio, the Americans killed 10 vietcong to every 1 American soldier. Also the war ended not because "they won" but becuase it had very unpopular support amongst the American people so the politicians decided to leave or "pull out". Vietnam was a strange war it was not a war to take terroritory, the Americans got into that war becuase an American base got bombed which was an act of war, and we were originally just there to support the south vietnamese becuase they were going to get overthrown by communist north vietnamese which were killing anybody including woman and children in south vietnam.
So your logic is false and somehow I think this is an arguement so you can keep playing your blue suit trolls without farming and crafting powerfist.
But anyways glad this stupid cold war crap and communist fear is over. Now we can all play fonline together.
