In December, 2017 the Palestinian Authority, now issuing stamps as the State of Palestine, issued a pair of stamps for "Palestine Teacher's Day". The stamp was printed for the Palestinian Authority in the Kingdom of Bahrain.
The stamp depicts a teacher in the colors of the pan Arab flag, pointing to a map of what they call Palestine, meaning no Israel, or "From the River to the Sea".
The problem with this issue is not the misinformation here, but that a teacher should be teaching this to children. In this frame of mind, where can there be co-existence?
