In Oman they do take UAE money at some places. In UAE GCC Currencies are acceptable at places like Carrefour hypermarket. I am not sure about Bahrain , though Carrefour has branches in most gulf countries, I am not aware of one in Bahrain.
See website http://www.carrefouruae.com/ they do have a Geant however http://www.geant-bahrain.com/ By the way ATM cards work across GCC so that may be a better option as you will get the cash in the currency where you are. You can also use credit cards or pre-paid Visa cash cards. Checks are not acceptable.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
