Do you think they could have all the weapons to wipe them out without the Funds the US sends them?
Of course. They dont need any money from the US to wipe out the Palestinians, but in order to protect them from the entire middle east, who wants them dead, the US funds are very useful. The fact is, Israel already bought many F/A-18s in the late 80s, early 90s. When i was in the Navy, my aviation squadron VFA-125 in Lemoore, California, trained F/A-18 pilots, inculding Israeli pilots. They bought the things, the least we cold do is train them how to operate them.
I believe i heard something recently about them having newer Raptors, but i havent checked to see if thats true, regardless, it wouldnt take many F/A-18s to flatten Gaza within a few weeks. I dont know how long it takes to fly to Gaza, im guessing not long when flying at 600 miles an hour, but once they returned and landed, you could have them refueled, and fully loaded with bombs within about 30 minutes, tops.
On the subject of bombs, i would imagine they already have far more then they will ever use in any situation, and you could keep bombs indefinitely if you wanted. Typically you will have thousands of unarmed bombs and missles at your disposal, and when it comes time to use them and you are the ordinance guy, you go to the explosives storage sheds which are lined up about 500 yards from the aircraft hanger, you grab the appropriate exlosive for the weapon you are using, and you load the bomb or missle with it. Im telling you, these sheds are FULL of explosives, and you have to remember, i was at a training squadron where live fire practice isnt common at all. I cant even imagine how much they would have on an Israeli flightline. I would think tons, literally. Enough for years of combat sorties.
