The problem with this is that 'getting back' at non-whites by breeding with their women is inherently unequal; essentially lopping off their finger after they've severed our limb.
There is a clear racial hierarchy, well established through contact with many different non-white tribes. Every non-white people that has laid 'conquest' upon whites, always exalts white women.
Genghis Khan's descendants had red hair and green eyes, because he took exclusively white women for his main brides.
The moorish kings demanded 1000s of specifically blonde white women as tribute while they were ruling spain. And interestingly enough, the moorish princes eventually became blonde after their shitskin ancestors secured the highest quality mates(aryan women). I had sources for those blonde princes but I can't seem to find them.
And from the Ottoman empire:
Circassians, Syrians, and Nubians were the three primary races of females who were sold as sex slaves in the Ottoman Empire. Circassian girls were described as fair, light-skinned and were frequently enslaved by Crimean Tatars then sold to Ottomans. They were the most expensive, reaching up to 500 pounds sterling and the most popular with the Turks. Second in popularity were Syrian girls, with their dark eyes, dark hair, and light brown skin, and came largely from coastal regions in Anatolia. Their price could reach up to 30 pounds sterling. They were described as having "good figures when young". Nubian girls were the cheapest and least popular, fetching up to 20 pounds sterling.
White women were literally so prized that one of them was worth more than dozens of their own women. And look how the Ottoman royal children turned out.
And let's not forget the barbary slave traders, that went all the way up to Iceland to secure sex slaves to sell to fellow shitskins back in the mediterranean, that probably made them filthy rich. The blonde aryan women were probably worth more than their weight in gold.
When you notice that people like Assad and other high-class middle-easterners look european, it's not likely because of some long-held european dynasty hold out from the greco-roman period, but more likely the sultans, omans, and princes securing the most attractive, and thus whitest women they could, eventually whitening their bloodlines.
And in modern times, only a basementdweller couldn't see this obvious racial hierarchy in play today, where shitskin men would quite literally fight to the death for the privilege of securing a white female.
Hell, even chink men consider it as bringing pride to their country if they secure a blonde woman.
Compare that to white men doing the opposite with a chink; a social no-no with connotations of low-status, betaness, and unspoken acknowledgement that the man was rejected by white women and had to settle for mediocrity.
So, according to widespread consensus, a non-white male securing a white female is an achievement, while a white male doing the same is a failure or a low-achiever.
