Leunig has also stated his opposition to the Israeli government. Three of his 2004–2006 cartoons drew letters of protest nationally and internationally in relation to this. The three pieces took as their subjects: IDF bomber pilots (13 April 2004); Sheikh Ahmed Yassin's assassination order from Ariel Sharon (11 January 2006); and the renewed Gaza occupation (12 July 2006). A fourth piece was refused publication and has since been more widely criticised for potentially confounding his opposition to the policies of Israel with an antisemitic, generalised subversion of the Jewish experience, by relying upon a reference to the Jewish Holocaust. This cartoon came to international attention after it was entered in an Iranian competition conceived by the newspaper "Hamshahri" as retaliation for the Muhammad cartoons controversy. Leunig denied he had submitted the cartoon as an entry to the competition and said "I've been set up horribly, maliciously." He demanded that his cartoon be withdrawn; the newspaper did this and also apologised to him. It later emerged that the cartoon had been submitted as a prank by Richard Cooke, a web contributor to the Australian comedic team "The Chaser".
