That’s absolutely not true, provisional states are very much real. There was a provisional German state after the collapse of the German Reich that existed from 45-49, before the creation of East- and West- Germany. There also was the British mandate for the area after the collapse of ottoman empire. So in a way there also was a provisional Israel.
The rest you write here is jibberish to me, but sure, the Isreali have been genociding Palestine for 70 years, more than doubling their numbers in the process. Seems like they are the least competent genocides in history.
