Iranian Supreme Leader Ayatollah Ali Khamenei said in a November 1, 2023 address that aired on Channel 1 (Iran) that "death to America" is not just a slogan, it's a policy. He continued to say that Western countries could not "make excuses" for anti-Israel and anti-American protests in England, France, Italy, and the U.S., and this is why there are claims that Iran was behind rallies in England. Khamenei mockingly asked whether these rallies were organized by the London Basij or the Paris Basij.
Ali Khamenei: "The situation between America and Iran is this: When you chant 'Death to America!' it is not just a slogan – it is a policy. I have stated the reasons previously. For many years, from the 1940s to the 1970s – that is 30 years – the Americans did everything they could do against the Iranian nation. They hit Iran in any way they could – financially, economically, politically, scientifically, and morally.
"If it were not for America's support, if it were not for the support of U.S. weapons, the corrupt and artificial Zionist regime would have been destroyed in the first week. It would have collapsed. The Americans are behind this.
"In Western countries – in England, France, Italy, and various U.S. states – people took to the streets in large numbers, chanting slogans against Israel and in many cases, against America. This tarnished [Western] reputation. They really do not have any remedy for this. They cannot make excuses for this. That is why we saw some idiot saying that Iran was behind the rallies in England. Perhaps the Basij in London is behind this... Or maybe the Basij of Paris."
