The US-Israeli attacks on Iran have taken a new form. After the death of Iran's Supreme Leader Khamenei, Lebanon entered the war zone as Hezbollah and the Houthis launched attacks on Israel. Experts say this is revenge for Khamenei's assassination. The Israel Defense Forces launched a counterattack on Hezbollah bases in Beirut. Hezbollah, which was formed in 1982 with Iranian support, has attacked Israel in the past. France, Germany and Britain have declared their support for the US. There are concerns that these developments could lead to a third world war.
