Because, as I have repeated and repeated here, the jihad is forever, and not subject to negotiations. From UPI, :
Lebanon’s Shiite militant group Hezbollah said it would not disarm in conformity with U.N. Resolution 1559 even if Israel pulled out of a disputed border area.
Hezbollah’s Deputy Secretary General Sheik Naim Kassem was quoted Tuesday in the daily An-Nahar as saying that armed resistance would be necessary even after a possible Israeli withdrawal from the Shabaa Farms area in order to deter Israel and stop it from violating Lebanese sovereignty.
“The resistance movement is not merely aimed at liberating Shabaa Farms … We need to keep up the resistance to protect Lebanon and defend it from Israeli dangers,” Kassem said.
