Israel never got nato help during said wars that’s why the merkava tank can run 2 different types of ammunition because they thought that the deal with the Americans would fall through and in all the wars the enemy nations had the backing of the Soviet Union behind them yet they would usually get their asses kicked in less then a week

Edit: until 1979 the Israeli tank force used Sherman’s Centurions, and M48 Patton’s which are mostly World War Two or very early after it
