And what better tool than to plant a disruptive, blackmailing, violent entity to do your bidding placed in a very strategic place. All of Israel's neighbors and even near-neighbors would remain under the blackmail: They follow the imperialists' line or else! The losses to those countries' progress have been enormous over the generations and will only mount.
The job of the resistance is near impossible as the Turks, Azeris and a large number of Arab Muslim countries(KSA, UAE, Jordan, Morocco, Egypt etc.) are traitors and in active collaboration with the Zio-US.
It may need to wait till China displaces the Zio-US from its position as sole hegemon to have another crack at destroying the usurper of Palestine.
Zio-US and the western imperialists like UK are bad enough but when you have neighbourhood traitors on top, it makes the job that much more difficult.
