You are probably correct that our pledge of allegiance is not an oath. The US Oath of Allegiance is: Solemnly, freely, and without mental reservation, I hereby renounce under oath all allegiance to any foreign state. My fidelity and allegiance from this day forward is to the United States of America. I pledge to support, honor, and be loyal to the United States, its Constitution, and its laws. Where and if lawfully required, I further commit myself to defend the Constitution and laws of the United States against all enemies, foreign and domestic, either by military, noncombatant, or civilian service. This I do solemnly swear, so help me God. So, it is similar to the Pledge but not exactly the same thing. You are right I was wrong. I believe a similar oath would be fine for Israelis but do not accept the addition of "Jewish" as it would not be acceptable to citizens of other faiths of whom there are many.
