So now since everyone agrees there’s a need both for full time Torah learners in Yeshiva as well as full time soldiers in the army, given the fact that less than 1% of the Jewish population in Israel seek to be full time Torah learners in Yeshiva, whereas a large percent of the population is happy to enlist in the Israeli army, we clearly realize there’s actually a shortage of full time Yeshiva men while there’s no shortage of full time soldiers.
Therefore anyone with any intelligence realizes we need to draft more men into Yeshivas. And that there’s no need for more men in the army, which is already fully staffed by the large majority of the Israeli population who refuses to learn Torah full time thereby leaving that very needed duty of more Torah study to those who volunteer to serve in the Yeshiva as Torah men.
The obvious conclusion is to not only allow but to encourage more men to go into Yeshiva rather than the army.
