Mongols killed more people in merely 2 years ramphaging in Central Asia, practically genocided every single major city, towns, villages. it was recorded by contemporary sources that a big city of 100,000 people had less than 50 survivors living in slave like condition a couple year after. And that was all done with bows and arrows and Mongol's favorite civilian-massacring weapon, the axe. They'd drive up all civilians to an open plain outside city walls, count them, allocate every soldier with a "quota", order the civilians to kneel, then axe or slit throat all of them.
and they loved piling up human bones into piles like those, this one is buffalos/bisons but Mongols had human skulls and bones intead, Beijing had a huge white mountain of that after Mongol conquered it and slaughtered every civilian, and they did this in Central Asia too, often divided into 3 piles, one for men, one for women, one for children. Imagine countless children and infants small skulls piled into a mountain. People these days have little idea of just how utterly brutal and savagery Mongols were. They think muuuuuuuuuh Nazis were evil. Nazis were total angels compared to Mongols.
Point is, if Germans wanted jews in Europe dead, they would all be dead.
Most jews died near end of war coz Allies bombed the european railway infrastructure and caused massive medicine and food shortage. so diseases began to go ramphant in camps. Ann Frank didnt die of gas chamber that bitch died of typhus. Mind you, a signifcant casaultie in Battle of Stalingrad was typhus too, it was just reality of that time due to no antibiotics.
