The Chief of Staff of ZAHAL normally has a four year tenure,Period. Its not a question if he is a great warrior or whether politics come into play. That has been a decision based on allowing other Generals,Colonels etc to advance up the ladder, so to speak. There could be nothing worse in a true democracy, where you have old, geriatric and senile generals in charge of an Army. Notice the average age of some of those generals in those unmentionable non democratic countries. Have a nice day.
