It is true that people in general are not equal, because of their individual differences. And since a "race" is a collection of individuals, it is not true that races are equal either. Your are right to reject these doctrines as obviously nonsense.
Why the West became superior is a long story. It goes back to the Greeks and Romans. There were a number of main factors: 1.
Tradition of rational inquiry. Rational inquiry means trying to find relations of cause and effect a) that comply with the principles of logic, and b) without referring to supernatural beings as part of the explanation. This is the basis for science and technology, and rational thinking in general.
2. Development of institutions for limiting government power. This enabled capital accumulation, which is the precondition of the greater wealth of the Westerners, which other nations are now copying.
3. Prevalence of Christian ethics among the West, which, for all its faults, gave the West a more individualistic and humanitarian outlook, compared to other cultures. However, in the final analysis, all the achievements of the West are still the result of individual human action.
People from Africa, Asia and so on, raised as Westerners, are capable of acting by the same lights. However in reality, the Westerners have an advantage over all the non-Westerners, even those raised in the West, because the Westerners grow up in Western households, and have received the traditions of their ancestors with their mothers' milk. That's why the West continues to be the fountain of modernity, and why the best all the other peoples can do is copy the white man.
And yet people from what you term "inferior races" do just as well as everyone else when they are raised and educated in the west. Which means that you are just a racist troll. You ignore the facts, you have been doing it for f***ing months.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
