according to me,
If Pakistan buys Sukhoi 35, it will be beneficial for India.
Probability of war between India and Pakistan is really low, as long as there is Civilian rule in Pakistan.
Now, Russian equipment is actually cheaper to buy, but very expensive to maintain.
And pakistan would have to actually pay to Russia, in one form or another.
So, although the SU35 will give PAF the required edge, but at the same time, it will also suck up the already tight defence budget of Pakistan.
If PAF commits to SU35s, Pakistan Military as a whole will have to cut corners.
Not only this, The IAF is very much familiar to the flankers.
yes, SU35 is much advanced than SU 30mki.
But, It still is a flanker.
Being the largest operator of the flankers IAF is very much familiar to the planes overall.
yes the advantage is there for PAF, but it will not be a gamechanger.
...Just my take.
