How the hell was the US embassy compound in Baghdad breached?

The attack on the US embassy compound in Baghdad is a dangerous warning sign of hostilities to come. American embassies are, in the mind of angry anti-US protestors, a symbol of the Great Satan. They are more vulnerable to attack in foreign parts than any other foreign embassy. The brutal attack on the US consulate in Benghazi, Libya on September 11 2012, ended with the death of the ambassador Christoher Stevens and three other American officials. A truly shocking event which should have served as a forever reminder that in potentially hostile environments, the US embassy has to be protected with a formidable presence of Marines to be a deterrent to anyone attempting to breach the perimeter walls. And yet that is exactly what happened in Baghdad. Hordes of angry Shia militia supporters managed to break down a door and gain access to the reception area. Only now after the violence of yesterday has the Pentagon sent another 100 Marines to guard the embassy. Surely when the airstrikes were approved to target five Kataib Hezbollah bases in Iraq and Syria, Pentagon and State Department officials must have considered beefing up the embassy Marine presence prior to the air raids by F-15E Strike Eagles. But apparently not. The extra 100 Marines had to be rushed in as an afterthought. It seems extraordinary to me that no one predicted there would be a violent reaction to Sunday's airstrikes which killed 25 Shia militia fighters. How bad did it look for America's prestige around the world for Shia militia supporters to break into the US embassy compound, supposedly designed to keep hostiles out? Within hours, Mark Esper, the US defence secretary, was forced to send not only 100 more Marines to the embassy but ordered 750 troops to leave immediately for the region, and warned off another 4,000 to be prepared to move. All too late. All deployments looking like the Pentagon panicking to fill in the gaps when it should have been pre-planned before the airstrikes were launched on Sunday. As has happened in the past, Iran is calling the tune and Trump is being forced to send yet more troops to the Middle East when what he really wanted to do was bring them all home. Sorry, Mr President, but you're never going to be able to do that because Iran will always be plotting the next outrage. Iran's proxy militia in Iraq will be under new orders to step up attacks on the US presence in the region. It's inevitable. That wily General Qasem Soleimani, head of the Iranian Revolutionary Guards Quds Force in charge of stirring up trouble for the Americans throughout the Middle East, is a master strategist and determined enemy of the US. He will see the breach of the US embassy in Baghdad as a great victory. Those US airstrikes on Sunday have opened up a can of dangerous worms.
