If Pakistan is directed to buy either the F-15 or the F-18, it should only do so as part of deal securing A huge increase in Pakistani Exports to the US to allow Pakistan to afford this purchase.
For the US it would “re-balance” the relationship with Pakistan and bring it somewhat out of China’s orbit, but would open Pakistan up to deeper US political relations with “civil society” groups.
Of the two platforms, the F-15 offers a superior platform with superior sensors, but will Pakistan be allowed to purchase the F-15 with all the bells and whistles, even if it can come up with the money.
One major positive of operating the F-15 would be having a platform that will be able to match any 4.5 generation platform in the region, if allowed to carry modern EW equipment.
2-3 squadrons may be all that Pakistan needs to maintain air superiority (each plane can carry up to 22 amraams), but Considering all the strings that will be attached, it could be another pressler amendment saga waiting to happen
