world changes and interests change and Russia has realied its interests can no longer be served by backing india alone.
Russia gains a lot more by having Pakistan as a friendly nation
just think what it can bring for Russia in the Muslim world and Central Asia.
But anyways
Pakistan isnt going to buy these Mig-35s anyway
Our next purchase will be J-10Bs or J-20s and from now on we will be moving towards a "manufacturing model" along with China and as Chinese tech keeps maturing so will our manufacturing capability
China and Pakistan share borders and they are here to stay and you can't change that any time in the near future while US and Russia are far off regions except Russia has started to acknowledge the potential of good relations with Pakistan.
Just think for a second:
Would USSR break if Pakistan was with them?
Other than some money from purchases, what exactly has india given them?
why didn't india attack Pakistan and save USSR?
