I would love to know the criteria used for the above classification.
Turkey and Israel are two most powerful nations in the Middle East. Israel has slightly better Air Force and nuclear strike capabilities. In every other category I'd say Turkey is superior. Israel has very good armor however, based of M1A1 platform.
Then I would say a tie between Iran and Egypt. Iran's economy and political state is hindering it's ability to modernize it's army. It has experience in unconventional warfare and can be effective one way or another. Egypt is a strong nation with good overall Navy, Air Force and Army. It's ground troops need more funding and better training, however. The economy does not help their case.
After them it's Saudi Arabia and Saudi Arabia is catching up fast. But, political structure hinders the ability for the army to develop. Recently the crown prince sacked many military leaders to modernize the leadership and develop the army. So we will see results in coming years.
Everyone else has no need to develop an capable army and aren't looking for war.
Care to elaborate on the point regarding Saudi Arabia?
