The relevant question is not whether half is enough or full is a must. The relevant question is "can it be that whoever choses not to enlist can dump danger and duty on somebody else, who may also have concerns, but realizes that it would be unfair to leave it to others"? It is not 50% of each group (orthodox, secular, wealthy, poor etc..)evenly distributed, whole groups are exempt to begin with. The 50% which according to GL is enough may soon become 100% of only group in our society. It is a matter of basic justice which for GL with other issues is usually highly important. Also the slogan was not "one nation - one army", but "one nation, one recruiting (system)" and came as a response to the orthodox slogan "one nation, one religious conversion (system. So GL's fascisct slurr was demagogery pure.
