It's better to be Bulgarian

A couple of years ago, I predicted a different ending. I told my husband that they would in the end let the Bulgarian nurses go and execute the Palestinian doctor. The outcome was slightly different. They were all let ago, and the reason? The Bulgarians now part of the EU (something they weren't at the beginning of the incident), gave the Palestinian doctor citizenship. He became Bulgarian, and he was released with the nurses.
Here is my question: why did none of the so-called brotherly Arab countries even think of adopting the Palestinian doctor so they could protect him?
Like I said, it's better to be Bulgarian.
