To be honest, he’s kind of right.
Sort of like how a third world nation thinks that having some rifles against the US military will actually make a difference.
It’s not like bringing a knife to a gun fight, it’s like bringing a rock to gun fight.
Tell that to the people of afghanistan who effectively stopped 2 superpowers using AKs. So much for your (and his) theory.
To fight guerrilla warfare you have to out number them by over ten to one.
One guerrilla can tie up ten solders on average. Yeah you can bomb the place to rubble but it will work only if you know where they are.
Then why couldn’t over a million troops, with jet aircraft, helicopters, tanks, battleships, missiles, smart bombs and every technology of the time, couldn’t defeat peasants armed with AK-47s in Vietnam?
