It doesn't change the fact that in this high tech era, it's necessary to have a fighter jet that can perform crucial tasks without being interrupted. Also it's become important for countries to diversify their defence procurement.
Israel is most definitely going to diversify and has been working steadily towards fostering relations with countries that has production power and can supply Israel in case the US gives it the cold shoulder. India, China, (Russia), and most likely UAE from backdoors. And most likely some EU countries as well.
I believe F16 V, and EF T3-4 could very well be the fallback solutions.
