@The Eagle a balanced and logical post!
The point is Sino-Pak-Rus axis wishes to make SCO a comprehensive and long term mechanism of Peace and Security in Eurasia. That is why Pak didn't protest/resist Indian enrollment.
However, it is sad that Indians have opted the opposite side. Be it BRICS, AIIB or SCO India was accomodated above its weight. This accomodation hasn't brought any positive outcomes.
Of course, India is a big country and a big market. But this is also more of a hype than life-changing/world changing paradigm shift.
The emerging vectors of Pak State Policy after 20 years of hibernation are telling.
Too early to celebrate, since, Pak Policymakers have a unique talent of messing things up pretty badly. 70 years of experience!
Most important thing however is economy. Amazing that Pak hasn't banned imports of everything except feul and edible oils.
Furthermore, as Pak State slowly announces its natural resources.... expect more troubles from within... the signs are already clear... Zardari League and Nawaz League are going to create big mess. Please, remember Angola, Nigeria and South America.
Having resources is one thing and being able to take advantage of them for advancement of State and People is another.
Multi-dimensional War!
Nobody is going to allow Pak State to become a Great Regional Power of Global Consequence that easily. Neither friends nor foes. Cruel World.
All the best,
