The war between the US and the countries with large Shia populations and corresponding Shia militias has been started by the US by murdering Suleimani, a top Iranian general, on a diplomatic mission between Iran and Saudi Arabia mediated by Iraq. He had to give to the premier of Iraq the answer of Iran to a former message send by Saudi Arabia. These negotiations have been suggested by the US. So, we have one of the worst imaginable crimes in international diplomacy - murdering participants of negotiations. The reaction of the Shia militias of different countries, in particular, of Lebanon and Iraq, as well as of Iran, has been immediate and strong. They have all promised revenge, and revenge in the form of dead US soldiers. The Iraq parliament has voted that the US forces should leave the country. On January 8. 2020 Iran has attacked US bases in Iraq at the same time when Suleimani was murdered. Two of the Iraqi Shia militias have also announced the start of their revenge actions, and a US base has been attacked by Iraqi militias too. The Hezbollah in Lebanon has announced that in case of a US retaliation they will also start rocket attacks against Israel, which they consider as being involved in the murder of Suleimani too.
