Israel does not have the death penalty except for genocide. Besides, a life of hard labor is more punishment than merely shooting them.
What kind of hard labor? They have to empty their own wastebaskets?
Their cohorts use their incarceration as a pretext for more mayhem. If the terrorists are planted in the ground like onions, their supporters would not have violent outbursts to free them. It can be argued that the stated intent of terrorists, particularly Hamas terrorists, is in fact, to commit genocide. Their intent is in their charter. That being said, the government in Israel should repent of its past error regarding the use of the death penalty.
