Libya is a total chaos, Tunisia has her hand full with domestic terrorists returning fron Libya, Syria and Irak , and Algeria will never put her troops under a foreign command firstly, and secondly will never send her troops to fight in a country to restore a government.
Algeria is a member of the non-allied 77, I can't see Algeria changing her policies to join a group, I think neutrality will a cornerstone of her foreign policy. Tunisia and Algeria have always strong strategic ties.
Language does not define one's roots...the real Algerian language is "darja" the spoken local dialect that 100% of the population uses and understand...Classical arabic was taught in Algeria after the independance of the country and few after 60 years of independance masters it..French is still the dominant language in business. Several berber language are still spoken and used in daily life despite the government hurdles to mute it.
North Africa is all berbers. They are muslims, but Berbers, more tuned to the west than to the East.
The Bush plan of the greater Middle east is being put forward and we can see it now in Iraq. We are living the her dismemberment. I am afraid that Syria, Egypt, Libya and KSA will be living the same fate.
