It just gets worse.

Sen. Barack Obama’s Chicago church published an open letter from a Palestinian activist that labels Israel an “apartheid” regime and claims the Jewish state worked on an “ethnic bomb” that kills “blacks and Arabs.”

The letter, discovered by the blog Sweetness & Light, was published on the “Pastor’s Page” of the Trinity United Church of Christ newsletter reserved for Rev. Jeremiah Wright Jr., whose anti-American, anti-Israel remarks prompted the presidential candidate to deliver a major race speech last week.

“I must tell you that Israel was the closest ally to the white supremacists of South Africa,” wrote the letter’s author, Ali Baghdadi. “In fact, South Africa allowed Israel to test its nuclear weapons in the ocean off South Africa. The Israelis were given a blank check: they could test whenever they desired and did not even have to ask permission. Both worked on an ethnic bomb that kills Blacks and Arabs.”
