Can you provide a source for the cancelation and that reasoning (ie suppliers refusing to work with Turkey, and which suppliers) . I haven't been able to find that anywhere (doesnt mean it isnt true, but It doesnt really make too much sense to me given turkey makes many US and European electronics and weapons platforms at home under license. If that were the case then all of Turkey's indigenous projects would have already been put on hold, including Ada and Istanbul class ships. All turkish designs use American weaponry and eurpean radars (for now). That being said, in Pakistan's case, such an embargo would make little impact as Turkey makes most of the electronics that Pakistan is interested in, and it can/would use Chinese weaponry equip its vessels (C-802 instead of Harpoon, FL-3000N instead of RAM). The main issue would be a medium range SAM, but China has one available if European options dont pan out, so does south Africa, amd Turkey will have its own weapn systems soon as well with Hisar and Atacama.
