PDF is not the Pakistani Establishment! Even without going through the UNSC, unilateral sanctions by America and its allies along with trade, remittance restrictions, blacklisting, import/export curbs... Far better naturally endowed countries (Russia, Iran, Venezuela) have been left with their potentials greatly curbed. In contrast, Pakistan would face a dire future. It is a reality which has never escaped Pakistani planners.
And I don't think the General is saying to defy Washington; he's been actually accused to be pro-Washington. He is the antithesis of General Hamid Gul: Both patriotic but very different way to align Pakistan globally. Remember, in his other piece on PDF he even went onto say that Pakistan's war in the erstwhile tribal areas was Pakistan's 'own war', a position which doesn't endear him to many on this forum. In that interview, he even called the American invasion of Afghanistan after 9/11 as a possible 'knee jerk reaction'--a position which runs contrary to what what many PDF members say, you know, 'Afghanistan Bahana, Pakistan Nishana'.
