Kurds are also "browns" (they're an indo-iranic group) and what a great way to create a rally around the flag effect and make everyone think that not only their regime, but Iran's national sovereignty itself is under attack. Also, as I asked earlier, if we allow them to get their territory what's gonna stop other groups from doing so, including the baloch separatists who have, amongst their ranks, bin ladenites and other ISIS-adjacent extremist groups. You think that sets a good precedent, to let groups like that gain a greater foothold in central asia than they already have?
