I believe the recent official visit of the Russian Foreign Minister - Sergey Lavrov, has cleared up any doubts. Unlike america, Russia seeks genuine bilateral partnership. For the past few years, Russia has kept a balanced relationship with india, despite india going full swing into the american camp, particularly india joining quad.
Meanwhile america has a duplicitous track record, as we have all seen with AH-1Z deal, F-16s and now T-129s. It's a fools mentality that some in Pakistan still think that partnership with america can still be salvaged or that they could squeeze anything out of them.
Be it T-129s or Eurofighters, Pakistan is guaranteed to witness biased policy of the West (including) tiny britain.
Russia is not dictated to by anyone, nor is China, neither is Iran. It is these countries whom Pakistan should be seeking establish strategic relations with.
