My correction too - They are currently Tier #1. I had researched this long ago and they were amazingly high, though I read the tier ranking wrong.
However there have been a great number of publications that have cited the issue.

"In 2001, the US State Department released its first Trafficking in Persons (TIP) Report and ranked Israel as a Tier 3 Nation – the report’s lowest possible ranking. A Tier 3 country is defined by its high level of trafficking and its failure to take significant strides to combat it."

I had to research this for a paper I wrote in college, and at the time, the situation was abysmal. That was around when the Tier 3 came out and US funding restrictions were a possibility to be levied. It is better, but there still are 8500 slaves, >15000 prostitutes (legal), and a lot of actual trafficking through.
Much of the Israel trade is white trafficking actually, but much of it comes through Egypt, who at least at one time actually fared better in terms of slavery and trafficking as one of the better states in the Middle East.
Other than enjoying some kebabs, falaffel, matzoh ball soup and gefilte fish once in a while, I dont care for any of the countries over there. I do however have close friends who are Israeli, Palestinian, as well as others who are followers of
Judaism and Islam. I am no Zionist, and feel personally that such a movement did nothing for ensuring stability, and a LOT of US money that we dont have goes over there.
But at the end of the day, the point I was trying to make at the start but failed to was that if one is going to start throwing stones at the Muslim world in this thread, as in the other, they need to at least look at the balance of the population over there and assess guilt upon all. Because Im sure that many would gladly turn a blind eye to Israel's woes, yet call to nuke every last Muslim.
Disclosure: BAC wary of the whole mess over there and not caring to see any American blood spilled for any of them.
