Lebanese individuals might have been involved in Syria’s war from early days. Sheikh Ahmad Al-Aseer declared Jihad and went himself there couple of months ago with his fighters too for a show-off exercise, but permanent or independent Lebanese fighting battalion are not known to be present as of yet.
If I want to draft my cultural shock caused by Hezbollah on a chart, it would look to be at its peak now.
May be that shock started mildly in 2005 when Hassan Nasrallah thanked Bashar Al-Assad in public on March 8, just after the Lebanese protests at the time helped to push a foreign Arab army off the national soil.
Then the dramatic political events that caused the deadlock in the country afterwards pushed this chart up. Then it spiked around May 7th 2008 when Hezbollah attacked Beirut and Mount Lebanon for whatever reasons. Now, the chart is heading to infinity with Hezbollah’s fight in Syria.
