No any aircraft carriers ever protected Israel.
Sure buddy, you can certainly deal with all the surrounding enemies without American security umbrella.
You will do just fine without American radars and AA systems stationed all around the Middle East. You don't actually need aircraft carrier groups that are protecting your ass 24/7. You will be extremely ok without unlimited flux of interceptor missiles. Your airforce is totally independent as you produce your own jets as well.
Anyways, you obviously don't have a plan for a scenario without America. That gives me hope for the future.
We were alone against the coalition of Egypt, Jordan, Syria, Iraq supported by superpower USSR, and we prevailed.
What is now? Egypt and Jordan are in peace, Syria and Iraq are gone, USSR too.
What remained? - Severely beaten and isolated Hezbollah and Iran that is located 1500 kms from Israel, does not have any airforce or navy and can also only terrorize civilians. Plus queers for Palestine and Tucker Carlson.
