Certainly that is the case as long as the Arabs are both fragmented and militarily inferior to Israel. While the former may always be the case, the latter will not.
You've been saying this for years (usually with the cop out that it won't happen for at least 50 years), and sure, a lot sh**t can happen in that time.....but why and how do you think it's inevitable? Which Arab country (or countries) do you think are going to pass Israel militarily? Most of them are basket cases, granted a few of them have money to burn right now, and they are no doubt burning it, but those wells aren't bottomless, the tap is going to run dry and what then? The powers in charge will no doubt look to da Joos to blame (again) for the troubles of the masses and the masses will (again) swallow the hook of bigotry, but to what end? Even if they buy toys on par with the IDF, are they going to learn how to practice using them? Maintain them properly? Use them with together with other toys? If you'll remember the early wars fought here you'll notice the equipment was close in quality (certainly closer than now), the IDF was very much outnumbered yet still came out on top, over and over again. Arabs can't win wars.
Is it possible? Sure
Likely? I don't think so
Inevitable? No way
