WASHINGTON — Former President Jimmy Carter won't go unchallenged after his appearance next week at Brandeis University, where he is lecturing on his latest book about what he terms the Palestinian apartheid by Israel.

Harvard Law School Professor Alan Dershowitz will step on stage afterward to rebut the former president's remarks despite having been booted from an earlier booking to debate Carter on his assertions.

“I think the inaccuracies of Carter’s points have to be pointed out. Carter said he wrote the book in order to stimulate a debate, but he won’t debate. I’m debating him whether he’s there or not,” Dershowitz told FOXNews.com.

“If his chair is empty, then that’s his decision,” he said.

The book "portrays the conflict between Israel and her neighbors as a purely one-sided affair with Israel holding all the responsibility for resolving the conflict," reads the resignation letter. "In light of the publication of your latest book 'Palestine: Peace Not Apartheid' and your subsequent comments made in promoting the book, we can no longer in good conscience continue to serve the Center as members of the board of councilors."

The reaction to Carter's book has also stirred up accusations about Carter's alleged involvement on behalf of a known Nazi guard who was deported to Austria in 1987.

In an exclusive interview to Israeli national news agency Arutz Sheva, a former U.S. Justice Department official said he received a letter from Carter in 1987 asking him to go easy on Martin Bartesch, who was known to have helped murder Jews in the Mauthausen death camp in Austria.

"It always bothered me, but I didn’t go public with it until recently, when he wrote this book and let it spill out where his sentiments really lie,” Sher said. “Here was Jimmy Carter jumping in on behalf of someone who did not deserve in any way, shape or form special consideration. And the things he has now said about the Jewish lobby really exposes where his heart really lies.”
