To say Hezbollah is only defending is a darn shame. They are supported by the Iranian regime that denounces the Holocaust, on numerous occasions said they want to wipe Israel off the map, and support killing of non-combat civilians. The real difference between Israel and it's enemies is that IF Israel wanted too IT COULD carry out everything Iran wants to do to it's enemies, but doesn't. Time is running out for Israel's enemies.
