tahini -“Nothing is worse than taking and not giving back, contributing to the community is a crucial jewish mitzvah and value.
Yes Health some do not go into the army, some healthy young men take money from the govt in Israel and stay in Yeshiva and learn, leaving it to others to defend, feed and support them and their families. Others go to hesder yeshivas, learn and defend as well as giving back to society.”
Your post is nothing short of Kefira, but you might not be a Koifer, just an Am Haaretz with a poor upbringing. The biggest defense against an enemy is Limud Hatorah (learning Torah). Not part time like the Hesder boys, but full time – in regular Yeshivos!
