Not to mention that ALL of Israel, the West Bank, Sinai, Jordan and parts of Egypt would be uninhabitable for thousands of years.
What?
You mean just like Hiroshima and Nagasaki are uninhabitable?
The "uninhabitable for years" crap is from the old Soviet talking points to try to guilt the US into abandoning nuclear weapons.
Granted, there are ways to enhance a nuclear warhead to make it a long-term poisoning device (like a cobalt jacket) but those are really more scare devices than tactical or strategic weapons.
