In an article on April 12th interviewing a Belgian expert on ISIS and Muslim extremism, there is this quote:
"What they really want … is the clash of civilizations," he says. "Revenge for what ISIS claims the West has done to Iraq and Syria."
It is hard to believe that an expert on this topic would not mention the central role that Israel and its treatment of Palestinians and the Muslim Holy Places plays in this problem.
It is highly likely that he mentioned Israel as at least part of the problem, but CBC chose not to include that in the article.
