I've been to two of the seven - Papua New Guinea and Zimbabwe - and not felt particular danger in either. The Southern Philippines, where we were accompanied everywhere by a guard with an AK47 over his shoulder, and Nepal, where armed soldiers and rebels were everywhere, were much more threatening.
They toured Auschwits-Birkenau while they were there.
Those pictures brought tears to my eyes. I don't think I would have gone on that part of the trip.
Those are not pretty sites for sure .I visited there many years ago .... well to date myself , it was when the Berlin wall was still in existence . That was also a heartwrenching experience . But for sure Auschits was pretty grim .
When I was in Israel last year we went to their museum and they had all the holicost pictures and information and even live testimonies . I could not take it all . I was very distraught by it all .
