The red cross is owned by the Red Cross and by medical personnel. In an Arab country it is likely that the symbol the "Red Cross" would use officially would be the flag of the Red Crescent, which is the symbol used by the Arab member countries in. But the red cross would still have an assigned meaning one could not co-opt.

A white flag of truce has no equivalent, I think.... it is what it is.

Hm.

It IS a problem innit?
