PMLn is saying it's a copy paste of Thier policies and they'll be better able to work on these policies than PTIAnd who will ensure the implementation and sustainment of this policy irrespective of the political party in power. I know establishment plays it's part but establishment mostly focuses inward, and leaves outward facing policies on cruise control, only reacting to changing dynamics.
So at this they atleast "agree" with it but knowing the clueless political class of Pakistan
I am not sure if by agreement they mean they'll actually follow it
Please look at the content not NSA's middle finger
And people forget these policies were made by consultation with generals, politicians, proffesors, economist etc
So not coming out of thin air, PMLn, PPP were probably also consulted in some ways
