On June 20, according to the British Sky News, the Kremlin said that regime change in Iran was “unacceptable” and that the assassination of the country’s supreme leader would “open a Pandora’s box”. Kremlin spokesman Dmitry Peskov said Russia would “react very negatively” if Khamenei was assassinated. The comments came as President Donald Trump said he would decide within two weeks whether the United States would join Israel’s military campaign against Tehran, after he spoke on social media about killing Iran’s leader. “The situation is extremely tense and dangerous not only for the region, but also for the whole world,” Peskov said. The wider range of parties involved in the conflict could make the potential harm even greater, which would only trigger a new round of confrontation and increase tensions in the region. It was the Kremlin’s strongest rhetoric yet on the Israeli-Iraq conflict, which has raised concerns about the imminent loss of Moscow’s closest ally in the Middle East.
