Hezbollah and the Syrian war.

Hezbollah declared their support for Syria's Assad, which is understandable insofar that, along with Iran, he's their biggest backers.  Last week they entered into the Syrian civil war, attempting to fight anti-Assad rebels...and many have since died.  Today, rockets hit Beirut -- seemingly an attack on Hezbollah's home.

Put aside the modern concept of who is a terrorist.  This is primarily a war between Shia and Sunni.

Who's Shia?

• Bashar Al Assad (an Alawite)
• Iran
• Hezbollah

Who's Sunni?

• Most Syrians
• Hamas
• Al Qaeda

Well, you can imagine the craziness going on, and how Hezbollah entering the war, means.  If Hamas enters the war, the Syrian war would include three of the extreme factions -- the violent factions -- of Islam, from both sides.  That'd be a complete mess.  It's not that violent faction against violent faction is necessarily something to weep over, but the problem is that there will be a lot of innocent victims, old and young.  War is sloppy.

So, when you hear US politicians insisting that America arm the rebels, you might understand some of the skepticism and hesitancy on the part of the Obama Administration, to directly arm the rebels.  If the rebels win, but Al Qaeda seizes control thereafter, Syria becomes a breeding ground for extremism and those weapons are turned onto Americans.

Therefore, the best solution is a politically-driven one that has a peaceful transition, and the sooner, the better.
