I'd like to think that an 'atheist take over' would be through the understanding that secular education in North America is not all that bad. and a secular reading of the scripture is a great benefit for public rest. having lived through 5 wars and participating in one I'd probably stare at the eyes of the personnel that face me, usually when they understand I am a veteran I get a huge break and we end up drinking tea and have some small talk.
really though, after having physical discussions with people who in reality should be considered my rivals, you always understand that you can have a discussion with just about anyone. I had discussions with immigration officers who seem to sympathise with me for being Israeli, had discussions with Iranians, Palestinians, Egyptians, Lebanese, at the end of the day, you realise you are all in the same situation.
its a strange world we live in, when your real allies are those who understand you might as well lower your guard. I had an Austrian guy tell me at a pub in Tel Aviv a few days ago in proper Hebrew: 'There are way too many Germans here. looking at two young German women, I thought 'well it actually makes me relaxed'.
