I think we're being myopic here and making takfeer of the Mawlana prematurely. Ml. Fazlur Rehman is still an 'alim, regardless of what we may disagree with him on and to suggest that he has simply given a blank check to Americans to kill Muslims in Afghanistan is being unjust. As I said before, he may have made concessions where drone attacks would stop in exchange for opening the route (which is what looks to be the case). If Ml. Fazlur Rehman had not cooperated, then the this concession most likely would also not have been granted and the supply lines would have opened without his support and without the clause that would stop drone attacks. I don't think it is a religious issue because as I mentioned, then Muslim Americans are also fair game for takfeer. I'm not talking about immigrants, I'm talking about American citizens, who pledge themselves to the country and many have shown support for the army or are in the army themselves. Furthermore, it can even be seen as two kufr entities dealing with one another, with a Muslim member trying to find a balance between having all Muslims killed or few Muslims killed when there is no option available to have no Muslims killed.
