This is the third time in 5 years that this is happening and I am posting about it (Yeshivas are moving north out of danger, what about the protection of Torah learning?, Should yeshiva students move away from the South to avoid the missiles?). Three times in Halacha makes a חזקה, so it is fair to say that we can draw conclusions from the actions of the Yeshivas. What I posted then is as relevant today as it was then:
The Charedi world justifies the draft exemption for yeshiva students based on the following:
1. Torah learning protects everyone
2. The boys are engaged in מלחמתה של תורה
3. Talmidie Chachamim don't need protection
Based on these it would seem that the Yeshivas should stay where they are. If the boys who are learning are engaged in war just like the soldiers why should they abandon their posts? In addition if Torah learning protects, let them stay where they are and be protected by their Torah. Their move undermines the claim for draft exemptions and looks very bad. The soldiers are preparing to entering Gaza to fight while the yeshiva bachurim are fleeing to safer havens.
