IMHO the Arabs armies will continue to do poorly like it was pointed out earlier---poor junior officers, I totally agree with this. Also I think they still use old style Soviet tactics to fight against mordern armies. So they will pretty much will do poorly even in the future.
The time to start worrying about them, is if a Saladin or a Hannibal gets a hold of their armies, and exploits their strengths and or reforms them. This may still happen. Let's not forget they have a strategic asset in their oil.
