Life imprisonment in Israel is legal and the most severe punishment available under Israeli law during peacetime.
The death penalty is applicable for certain crimes in Israel, but has only been used twice, once illegally during the War of Independence in 1948, and once legally against Adolf Eichmann in 1962, with another four convictions in cases of political violence being commuted or overruled on appeal.
[1] Life imprisonment is mandatory in all cases of murder, except in certain circumstances when the sentence is sometimes reduced.
Israeli law also allows life sentences for juveniles under age 18 if convicted of murder.
Those convicted of terrorist offenses are not typically granted clemency or parole, and are usually only released in prisoner exchanges.
