I looked but I could not find any statements by Ken Loach concerning a boycott of Iran in light of their president’s statement to wipe Israel off the map. Nor could I find statements by asking for a boycott of Lebanon because Nesrallah wants to wipe all the Jews off the map. I guess he perceives Israeli actions as deserving of genocide. Given his unbalanced criticism one has to ask the question, "is he or isn't he"
