Finkelstein, author of, The Holocaust Industry, which argues that the Jewish establishment has exploited the Holocaust for political gain, has been refused entry into Israel:

The Shin Bet said Finkelstein “is not permitted to enter Israel because of suspicions involving hostile elements in Lebanon,” and because he “did not give a full accounting to interrogators with regard to these suspicions.”

He did have contacts with Hezbollah operatives in Lebanon a few months ago , he published articles about that, so it’s inevitable that he would be questioned on entry.

As to whether he was forthcoming, we are in a he said/she said situation.
