What makes you assume that they want to “help” in any form? A large number of the ones objecting are opposed not only to war but to the existence of Israel existing as a state.
Here is what it looked like 10 years ago when Israel tried drafting the Orthodox Jews kids into the IDF:

I read that there were over 10,000 at that protest.
Israel backed down because they hate for attention to be drawn to the fact that there are vast multitudes of Jews that oppose the existence of the “state” of Israel because it violates their scriptures.
I’m guessing that right now is not the time when “Israel” wants additional attention on their “Jewish State” identity theft scam. 😉
