Well it's not a denial, it's the reality that the TTP is not the same group as Afghan Taliban nor did Pakistan support TTP. In fact's you're in denial and in delusion if you believe the two groups are the same. Nearly every expert on this issue knows that the two groups are not the same. I have no beliefs on which group is true Taliban or not but TTP and Afghan Taliban are not the same group. They don't even work together, are independent of each other, let alone being the same group.
Bharatis as much as they want can try to combine the two groups into one to suit their worldview. However that won't change the fact that TTP has nothing to do with Afghan Taliban.
