Well the news came in 2006 that EU plans to sell EFT to Pakistan through Turkey but nothing happened i don't think Politics is the issue if UK can offer us Type 45 Frigate in 2013 they can sell EFT just give them money
This is not between Pakistan and UK but politics of the region.
Here is a scenario
India goes for Raffale so that Pakistan is not able to get the avionics for JF-17. Slaps US by not buying F-18's Still goes after heavy lift aircraft / awac and helicopters(still not signed).
Russia offers the Mig-35 as well as the SU-35 to Pakistan India demand more research in PAK-FA design deals with Pakistan in the limbo. India orders heavy lift helicopters from Russia and S-400 Russia invests USD 2 billion in Pakistan in oil pipeline and direct sale of JFT engine.
India slaps UK by not buying EFT. UK offers these to Pakistan US sanctions are there hence deal not possible.
Today US sanctions are not present F-16's are being sent PAF would only buy 100 as this was the initial order the rest would be catered for by JF-17.
Now consider this scenario to Iran - Saudi Arabia and you get your answer.
Same scenario to NATO - Russia
New lines are being drawn AFG is going to be a buffer zone to check both Iran and Russia. Russia knows this and hence enters Syria knowing that Turkey could block the access through Straits of Marmara . The only issue is how can Russia enter IRAQ ? Answer is simple Iran. The Arabs and Western powers do not like this. Arabs try to enter Yemen so that they can control the Gulf of Aden.
Pakistan suddenly becomes very important as it has Gawadar from where it can easily secure the Straits of Hormuz.
US can not provide F-15's because PAF does not want them and they can not offer the F-35 for some time as it would potentially swing the balance of power in the hands of Pakistan and India would go rogue...
The only potent aircraft that can come is the EFT and has US and NATO backing paid off by the ARABS.
Iran would not be able to buy ant Western aircraft other than the SAAB Gripen which does not fulfill the requirement of Iran. Iran would have be depend on Russia and China for aircraft with China on Pakistan's side only Russia will be available.
