From day one of the creation of the state of Israel it was incumbent for all members of society to accept responsibility for survival of the state. Men and women served in the armed forces, and remained in reserve units well into their forties. At the moment of beginning compulsory military service it was also apparent the death of thousands of rabbis and other religious leaders required offering exemptions for remaining men. The Tal law made sense. Ensure the survival of the Jewish religion and allow those who pursued religious lives to work for Israel in a non-military manner.
There are now 65,000 ultra Orthodox who are exempt from military service. Shaul Mofaz led Kadima into the Netanyahu government in hope of creating a viable coalition that would reduce power of ultra-Orthodox politicians and establish the foundations of an Israel in which all served in military or community service activities, including Arab citizens.
Mofaz announced he was leaving the coalition because Prime Minister Netanyahu refused to move ahead with ending ultra-Orthodox military exemptions. Bibi pleaded for more time and pleaded that confronting the ultra-Orthodox threatened the survival of Israel.
If one truly wants to engage with God in an intimate manner, engaging in community service not only allows studying the Torah, it allows one to practice what is stated in the Torah.
