It is not only leftests who have 2nd passports. I remember chatting with a a settler (with an American Passport) who helped his grandchildren qualify for their American Passports. I tell my children if they ever have trouble travelling never use their Israeli or American Passports, but their French ones instead. They will be safest that way.
