Multi-part answer: (1) US pledge is discretionary. You don't have to say it and it's not an oath. (2) US pledge is Judeo-Christian-Muslim inclusive - just a reference to "one nation under God". For agnostics, polytheists, and atheists, the pledge does not speak to them - but then again, the US pledge is not obligatory. (3) US Citizens do not lose citizenship if they don't make the pledge (see proposed amendment to Israeli oath). (4) Outside the context of schools, the US pledge is mostly used as a preamble (along with a prayer) in right-wing meetings. So . . . what is this Israeli pledge all about? It's about stalling settlement negotiations.
