This terrorist attack is carried out by United States not Israel since only US has this kind of capability and also has a history of carrying out this type of attack (in Iraq many years ago).

As for benefit, it is for an internal use otherwise it is not going to change anything on the ground. If you check the Hebrew media of the terrorist organization, they are selling this to the occupiers as a big win trying to cover up all their losses in Gaza and Northern border with Lebanon. The terrorists needed this specially after they were hit with a hypersonic missile: https://bitcointalk.org/index.php?topic=5500581.msg64537220#msg64537220
