UAE visa handbook:
"The three entry requirements of obtaining a visa in the United Arab Emirates (UAE) and its seven emirates (Abu Dhabi, Dubai, Sharjah, Ajman, Umm Al Quwain, Ras Al Khaimah, and Fujairah) are that you are not a citizen of Israel, that your passport doesn't contain Israeli stamps, and that your passport is valid for at least 6 months before your arrival. Information about the various UAE visa categories are explained in detail below..."
So sinks, what is the color of the skin of an Israeli that is denied entry to the UAE... and on what grounds are they denied?
Why did Zim, an Israeli shipping company, endorse the Dubai ports deal?
This is just business.
