Israel and everyone else appears to have made a mistake. Israel didn't install the THEL laser system that Israel participated in creating. The THEL was able to destroy Katyushas and Kassams. The land based device was big and costly...a desirable target. The mobile version is still under development. Israel already has installed the radar from the THEL program for use in targeting launch sites with mortars.
Wait a second. Maybe Israel wanted a reason to decapitate Hamas and Hezbollah. It unfortunately cost dozens of Israeli military and civilian lives and got worldwide support for Israel to carry out attacks. Maybe it was a positive but tragic decision.
The THEL is a weapon that can be deployed in the future when it may really be needed more.
