I think boosters are going to be necessary, but perhaps not quite as soon as people are arguing.

Also, it seems the Pfizer and Moderna vaccines were not made equal. Protection from Moderna is waning more slowly, and thus the booster regimen should probably be different across those two, and J&J people should be getting boosters NOW as it seems the first shot was not really sufficient.

The FDA only said "not yet" on boosters, not "no," so if it really does demonstrate significant success/help in Israel they may change their mind.
