How do you think Africans speak French, because they wanted to? No. Because French forced them to.
What about South America? They wanted to speak Spanish? No. Because Spanish invaded there and forced them to speak Spanish.
Wherever you invade a country, you force them to speak your language and make them believe what you believe in. That's what England, France, Spain, Portugal have done.
Ottoman Empire didn't. If we did, from Austria to Saudi Arabia, everyone would have spoken what we speak and believe in what we believe as a religion. So, in this case we're dumb. We should have tortured people to make them do what we wanted them to do, just like France, England, Portugal and Spain have done.
We were stupid enough to just collect taxes from countries we invaded. What did we get from Arabs? Backstabbing by allying with British.
So you can't say, "Ottoman Empire was torturing us bla bla bla. That's why we sided with British to defeat Ottoman." Because we were too stupid not to torture anyone. That was our biggest mistake.
