It is reported that , the only reason ISIS hasn't attacked yet in force is because they haven't decided on the mission's commander.

The Lebanese army isn’t so strong and Syrian and Iraqi armies are fighting with terrorists and it is hard to safeguard their own borders.

So France is going to send a three billion dollar package of weapons to Lebanon and the Saudis are going to pay for it.But It won't solve the problem anymore.

Saudi Arabia is the most culturally conservative Arab country and Lebanon is the most liberal, partly because of its one-third Christian minority.

Despite the vast cultural differences between Saudi Arabia and Lebanon, the Saudis want Beirut to remain exactly as it is—a freewheeling Arabic-speaking “Amsterdam” or “Hong Kong” on the Med.

But aside from all that, the Saudis feel just as uneasy about ISIS as everyone else. Never mind the ideological overlap between the upstart “jihadists” and the Wahhabi-backed monarchy. ISIS threatens every single government in the region. It would make permanent alliances with none and conquer all if it could.

The Lebanese, of course, are in far more immediate danger. They can feel ISIS' hot breath on their necks. The army has been scrapping with them along the Syrian border for some time now. A majority of Lebanon's population is either Christian, Shia, or Druze, and all three populations rightly see ISIS as a potentially genocidal threat to their very existence. Even the Sunnis, though, fear and loathe ISIS.

A serious invasion of Lebanon by ISIS could unleash a bloodbath that makes the war in Syria look like a bar fight with pool sticks and beer mugs. Every family in Lebanon is armed to the gills thanks to the state being too weak and divided to provide basic security, but people anywhere in the world facing psychopathic mass-murderers will fight with kitchen knives and even their fingernails and teeth if they have to.

The only good thing that might emerge from an attempted ISIS invasion is that the eternally fractious Lebanese might finally realize they have enough in common with each other to band together for survival and kindle something that resembles a national identity for the first time in their history, World Affair belevies.

Foreign armies don't do well in Lebanon over the long term. The Israelis managed to invade and occupy a large part of the country during the war in 1982 and even exiled Yasser Arafat's Palestine Liberation Organization, but they ended up fighting  against Hezbollah until 2000.

So ISIS will eventually lose if thrusts into Lebanon, but the cost could be unspeakable. Few of Lebanon's prior invaders murdered innocent people with such gleeful ferocity.

And f ISIS makes any headway at all in that country, West will get sucked even deeper into the great war of the Eastern Mediterranean will only loom larger.
