The Forever War: Home Sweet Home?

Progressing through this book, many of the Afghans talk of Afghanistan as their home and they fight with all of their hearts to defend their homes and families. It is very ironic that they have such strong emotions about their homes when the majority of their country is destroyed and now just rubble from countless bombings and battles. Gul Nabi was sitting on a brick wall looking at his destroyed house and the wooden planks used to make a grave for his entire family. The city of Khan-i-Merajuddin was nothing more than a graveyard with more bodies  than there were gravestones. When everything in their homeland is already destroyed, what keeps a man fighting? What else keeps them fighting and staying strong to their beliefs? The determination these people have to keep fighting is unmatchable; I have never heard of people fighting for their homeland when it is already in rubble.
