Look buddy if there's an army of beastly looking Asian men who just went through and killed off most of central asia in a wild killing spree, asking for your surrender, food and provisions, only an idiot would refuse and think that they'd be spared.
Why not, let me impose a special tax that you get because you're born as a special ethnicity. Ideal Civilization right? Even the Greeks would come to you and beg you to let them use your extremely civilized methord of collecting tax from one ethnicity to fill up their empty coffers.
While ethnic and religious tolerance was extremely high in the great and mighty Mongol empire.
Afghanistan is not only Pashtuns, nor was it back then.
I'm sure you wouldn't want to invite, welcome or give your land to INVADERS. It was an invasion, not hey Khorasan province mind if I take you over?
You have no right to tell me where my homeland is when you yourself came with Alexander. And or are remains of a Hebrew tribe.
You're mixing up two separate things, first you're talking about the totally just and needed for obvious reasons invasion of Khwerezemia.
And then talking about how bagdad fell about half a century later during Halagus invasion.
I don't think the Vizer would betray the fine and just caliph if he hadn't started sectarian differences. (Or insulted the poor guys poetry)
We got minimal resistance thanks to friends, and drowned the already small army.
Halagus entered with the intention of arranging a few marriages with the caliphs family and other influential people.
That's when one stupid Arab decided to take a potshot at the guy who just took over the city, and hit one of his top advisors. Pissing off the Khan greatly.
The Caliph said "it is the will of God" that you captured the city ect, ect.
And Halagu said "What will happen to you is also the will of God". Before promptly wrapping him in a carpet and getting him trampled by horses.
