When the Germans liquidated the Warsaw ghetto and deported the inhabitants to Treblinka they were met with armed resistance from a few people with firearms. It was quite a struggle to subdue the ghetto even though the Jews had very few weapons. In the end all were killed but it showed that it does not take a lot of weapons to make the evil machinations of tyranny a lot more difficult. So Dr. Carson was correct.
Interestingly, the other tyrannical mass-murderer, Josef Stalin, prevented his troops from assisting the Warsaw Ghetto Jews.
The irony is that many of the Nazi troops that would have been killed by a combination of the Russian forces and the Warsaw Jews lived to fight another day - in Berlin, which Uncle Joe Stalin paid for with lakes of young Russian blood.
