Well,Israel are one freaking tough bunch kicking butt from 1948. They can,and do,handle a bunch of crazy armies come crashing at their door on their own,so I guess they can handle it easily.Israel? I'm not even sure if Israel exist here... Even if, i don't think that such small, single country could be so important and powerful enough to justify being a subfaction. They would sooner be part of the Euro Alliance.
Similarly, Chaos Force would rather be part of the current Scorpion Cell, and there is nothing soviet in an Arabian side. Quite the contrary - an arabian side might have become part of the Allied forces instead.
Also, side-specific buffs are gone, and from Speeder's stance on them, i doubt they'll return.
The Arab before and in the 80s were normally on Soviet side because the Israelies are allies to the west whose enemy is Russia,so the enemy of my enemy is my friennd,the Arab did receive lots of aids from Communist countries so they are communist,just don't want to add a communist name on them.About chaos force,i will miss those guys. And the side-specific buffs should be more balance,not like apoc tank produce 20% faster,but some other more balance stuff like better map visibility,cheaper buildings etc along with disadvantage to balance stuff out
