The following is just my opinion: No Islamic country is safe for Americans especially women right now. That said, the Dubai in the UAE is probably the safest of the lot. After all, the UAE is the only Muslim nation that condemned Hamas for the attack on Israel.
Even in moderate nations, you are still dealing with hatred of Christians, which is always bubbling right below the surface.
Don't go if you're a woman. If you're a man, Dubai is fine for now. But keep your mouth shut.
I believe Kosovo also condemned the attack on Israel. But they are not Arab Muslims.
