NATO should not complain especially since gave the ground to India in Afghanistan.
Rather than labeling PAKISTAN as the reason for US failures, should have questioned Obama etc while signing LEMOA and pushing India into Afghanistan.
What NATO did for us despite all evidences of Afghanistan and India backing TTP from Afghanistan that too in presence of NATO/CIA so in the end we also needed a room to breathe. Those India and Afghan puppet Governments are blue eyed for US & NATO for their own interests so we have our own interests as well.
Mere statements are based upon what's cooking in there and looking for an opportunity to save face being failed in Afghanistan. The key of success was to support a Government of people and not of D.C like what US did in Iraq and same happened in Afghanistan yet, both countries are totally sabotaged. The peace of Afghanistan is linked with its neighboring countries if US really want it to prosper rather than using it as a containment point against Chian, Russia and PAKISTAN like the statement speaks volume.
US General may name a single country that is ever liberated by NATO/US and are living in peace and happily but none because, Washington always works for its own interests hence, sometimes we have the right as well. US chooses India over old ally as to say and gave full access to Afghanistan who is more close to Russia and Iran than why not name India for paving way for Russia and Iran being friends and ally. But naming PAKISTAN, Russia and Iran was necessary to inform D.C about Geopolitics change of CIA and put Trump under pressure that already threatened Iran recently while CIA reporting again to push against PAKISTAN and Russia too which reminds us about fake Iraqi WMDs.
Rather than accusing others to save face and do-more thing, need to deal with cancer within Kabul and all country so also, reduce the unlimited ANA Generals and eliminate ANA/NDS working/terrorism against PAKISTAN.
