I wouldn't call the decades long conflict in the middle East between Palestine and Israel, 'stability'.
There would be greater stability if Israel respected the UN resolutions it has ignored over the decades.
If Israel did not start evicting Palestinians in 1948, and continued to do so until present day, if Israel did not continue to kill, imprison, torture Palestinians, women and children, humiliate them, sexually abuse them, and treat them as second class citizens, there would be greater stability in the Middle East today.
If there is no stability in the Middle East, we know exactly where to look for the cause.
