I like the Cedar on the flag, but it's not representative. A Cedar lives forever, Lebanon is reborn every generation, Lebanese don't care much for nature, and sadly instead of being the one national symbol the Cedar has mutated into a variety of species depicting different warring tribes.
I suggest the Carrot as a replacement. The Lebanese have always fallen for old carrot trick. In the last century alone the Carrot has been dangled by Ottomania, France, Egypt, Iraq, Iran, Israel, Syria, Saudi Arabia, and most recently by France again and "U.S.A. U.S.A. U.S.A."
Every single time it has been chased by an ASSortment of Lebanese folks.
