The world is talking about what is to be done in response to the neuro toxins used in Syria. I hope that in making a plan to deal with this situation, which must not be allowed to go unchecked, a long term plan, which considers all scenarios, is carefully and thoroughly thought out. Already diagrams are out on the evening news detailing exactly what the attacks will hit, exactly what resources they plan to take out, and other details of attacks that will be made. (Personally, I don't understand this tactic of informing the enemy, of what will be targeted, and with what. There might be some part of the plan they haven't figured out.) There are so many considerations to make. There are so many players in this game.
Iraq borders on one side, and sectarian conflict is currently tearing the country apart, and unrest is nearing a boiling point as Shiite-Sunni factions are bringing the country to the brink of civil war. Already Iraq has been impacted by the situation in Syria, with refugees from Syria pouring over their borders. Another note here, refugees from Iran also pour over the borders. Not only do they pour over the borders, but elite troops from Iran follow them, and attack the refugee camps set up for them in Iraq, murdering the escaped citizens as an object lesson for all would be defectors.
Since we are talking about Iran, who has a powerful supporter let's examine how they may view an attack. Surely if a military strike takes place in Syria, Iran will react, and it won't be for their stated objective at the time. It will be to protect their territorial advantage, because Syria can at this point easily be over run by Iranian forces, in order to keep access to the coast through Qusayr and Homs. Of course their nemesis, and hated enemy, Israel is a straight shot through Syria as well. Lebanon is also of interest to Iran, and there are Shiite-Sunni tensions in that country as well. Those tensions will easily be manipulated by Iran, in order to achieve their aims.
