The only reason the huge scale of the holocaust happened is because hitler had the best army navy and air force in Europe.

But now there is NATO and the UN and multiple super power countries which is hard to say which one is better to pull that off and not be pressured to stop what you were doing. There were little people who tried to stop Hitler before the mass Genocide. But today on the same scale as what hitler did would almost be impossible to do without being stoped.
