OK, basically I'm very ignorant on the topic of Khilafah, but what I do know is that it's establishment is obligatory. Now, the salafi response regarding is always beating about the bush more so than anything else. Also, if we look from an historical perspective, the Wahhabi movement for all intents and purposes did form an 'alliance' with the Aal-Sa'ud. Whether it was viable or not, I'm not sure. Whether it was necessary I don't know. Whether it was the best decision, given that Aal-Sa'ud were complicit in abolishment of Khilafah (even if it was only a symbolic entity by then) is one BIG ?. So, it seems to me that Wahhabi movement's alliance with Aal-Sa'ud was a great display of political naivete. Some may even say treachery. So how do we explain all this, and where do Wahhabis stand on this issue, and by extension Salafis?
