It appears that it will not be possible to prevent the sale of fifth-generation fighter planes to Arab states forever, but it is certainly possible to delay this development by several years
Delaying the Release of Fifth-Generation Fighter Planes to the Arab States
Israel's aerial superiority remains a key component of its qualitative military edge in the region. Israel's airpower is central to its image and deterrent ability: it protects the country's airspace, provides the first and multi-arena response to both immediate and more distant threats, enables retaliation and retribution missions for attacks on Israel, and plays a central role in managing military operations on various fronts. However, Israel's aerial superiority has been eroded in recent years, due to a combination of two force buildup processes in Arab states – the improvement of their air defense systems and the massive acquisition of advanced fighter planes. For Israel to maintain aerial freedom of action in the next decade, it must have exclusive regional access to fifth-generation fighter planes, such as the F-35 (known in Israel as the "Adir").
