None of these outside countries from the West will put any boots on the ground in Lebanon - just money and weaponry.
So with both sides in Lebanon with plenty of money to buy weaponry to kill each other it certainly has the potential of being a bloody mess.
Long term , unless Iran and Syria are destabilized I don't see how the Muslims can lose this one
Sunni = Muslim, Shia = Muslim. The rest are Infidels.
The Sunni and Shia have their religious differences but they both know the Infidel influence in that region must be destroyed, and Lebanon is a good start. - tom
Tell Syria that they need to end their harboring of Nasrallah and quit interfering in Lebanon. If they don't turn over Nasrallah or at least boot him out of the country, do the same to them as was done to Iran.
This won't make the terrorists go away. It won't end the feud between the Shia and the Sunni Muslims.
It may however, give the democracies in Lebanon and Iraq a fighting chance by throwing those trying to overthrow them by force into disarray for a while by cutting off a primary source of funding.
On the home front, we would once again end up spending billions of dollars dealing with other people's problems that keep overflowing into the rest of the world.
We would also take a hit to our economy due to higher oil prices, though some of the other oil producing countries in the region might increase production and help mitigate price increases in exchange for reducing the regional threat that Iran poses.
We'd also be called murders, imperialists, and get blamed for every real or perceived problem in the middle east by the world's liberals.
However, I think the alternative is even worse. Iran is getting bolder and bolder, and appeasement is the rule of law at the UN. Things are going to continue to get worse, and once Iran has nukes it could very well get much worse very quickly.
