I'm not quite sure what your objection is? Are you generally against companies providing services related to warfare? Or are you specifically against providing services for the Israel/Gaza conflict?
If the former - if you are generally protesting commercial services for the military - then there are a lot of companies you need to boycott, before you get around to Amazon. Amazon is a small fish in the sea.
If the latter, then cancelling your Amazon account is pretty small potatos to protest the Israeli attack on Hamas. And I would have to ask: have you also protested the Hamas attack on Israel? While the whole situation is a mess, Hamas definitely started this particular fist-fight.
