I am traveling to S. Africa, Botswana, and Zambia. My US passport (US citizen) has an Israel stamp. Need I have any concerns re. safety? I'm a middle-aged female. Thanks, I'm traveling with my mom. and believe I'll be fine, but would like to feel relaxed about this question. I thought I heard some Jews have 2 active passports to relieve such concerns, but don't even know if that's possible. Thanks.
