The GCC, Egypt and other Arab states should adopt a modern pan-Arab approach towards their fellow neighbors, one that doesn't attempt to dominate other Arab states as Nasser and Ba'ath Iraq did, but it has to be a lot more aggressive than today's policy which is best described as; idle.
As for Iraq, it went off course completely since 2003's regime change. In the right environment, that is without Iran's heavy interference, without Al-Zarqawi's insane ideology and without the retarded exiled bunch that came to govern Iraq. The country should have integrated with the GCC as a fellow Arab and Gulf neighboring state whilst modernizing.
Lebanon and Iraq are in exactly the same situation, semi-stable but hijacked internally by its own constitution and system. Multiple military forces and 'good' relations with everyone out there. Massive protests in both states, but very unlikely to see major change apart from governments resigning. The system will remain, the only way to remove it is by extreme measures which are either a military coup, heavy foreign interference or a civil war. The latter would not do any good as neighbors will be fueling it and interference will skyrocket.
The region won't see stability if Arab states don't align with one another, form alliances and create a force that can maintain the stability in this region. Anything else will not work, Turkey's interference in Arab states is not welcomed and rejected continuously, likewise, Iran's interference is experiencing a negative response by Iraq's Shias.
Regional Arab integration is the most important thing as the Arab world is too vast for 1 single Arab country/entity to dominate events (not been the case for ages) and most of the challenges, problems and solutions require regional Arab solutions. Unfortunately most of the regimes in power, if not all, worry about their own throne before anything else. Like anywhere else. However in say Europe, something like the EU emerged after the internal infighting and horrors of WW2 (60 million casualties). There has not been anything remotely similar in the Arab world. ISIS, a few civil wars and prior to that wars against the Zionists which united the Arab regimes due to pressure from locals and the ideology of those in power.
The Arab street (people) want what we want (vast majority regardless of ideology) but the rulers see no need to implement such visions which could endanger their grip on power.
If/when the region gets really heated and big consequencees follow, things will change for the better.
We saw relatively peaceful revolutions in Algeria (military still controlling things but progress) and massive protests in both Iraq and Lebanon and demands of big changes.
Iraq and Lebanon face many of the same problems. Relatively weak central states, nonsense secterian political system, outside meddling and lack of genuine patriotic leaders.
If not for Saddam and the Iraq-Iran war, Iraq would have been a founding GCC state and it would have been the most advanced and wealthiest alongside Kuwait and KSA and much of what follower after 1979 would probably not have occured.
The solution in Iraq is for patriots to take power (military), do a much needed cleaning up (remove the useless constitution, remove all Mullah interference etc.) and clean up the old useless guard and political parties (ban every party following foreign orders) and open up for elections after a few years of cleaning up. Sadly not realistic but things really need to change. Cannot go on like this for another 16 years. No doubt after what we are takling about oxccuring eventually, question will be how much time will be wasted, lives and potential progress.
BTW even in recent years there have been a significant GCC (KSA, Kuwait and UAE mainly but not only) Iraq reproachement which says everything about what the future has in store given that all odds against such closeness (ties are now cordial with elites that fought against their country in the 1980’s and de facto against KSA) were low not long ago. Only sharing almost everything in common prevented this unnatural situation to continue and once the people will decide, the relations will reach levels 1 billion times higher. Goes for the entire Arab world.
Forgot about the very positive revolution in Sudan.
