So, just who is this top Iranian general the U.S. just eliminated? For many of us who watch and analyze news out of the Middle East daily, he was the world's number one bad guy. Qasem Soleimani has been in control of Iran's Quds Force for more than 20 years. His current greatest hits include helping Bashar al Assad slaughter hundreds of thousands of his own people in the Syrian civil war, stoking the Houthis in Yemen's civil war, and overseeing the killing of hundreds of Iraqi protesters recently demonstrating against Iranian influence in their country. But most importantly for Americans, Soleimani was behind the deaths of hundreds of American soldiers during the Iraq War. Last year, the U.S. State Department put the number of Americans killed by Iranian proxies in Iraq at 608 since 2003. The killing of Soleimani doesn't have the emotional power of the takedown of Osama bin Laden, and he wasn't even as well-known to Americans as ISIS founder Abu Bakr al Baghdadi. But in many ways, taking him out means much more in terms of saving current lives. Remember that bin Laden and al Baghdadi were mostly out of business and in hiding at the time of their deaths. Solemani was busier than ever, directing mayhem all over the Middle East and beyond.

For example, these last few days have made it clear to the whole world just how much Iran controlled just about all of Iraq and Iraq's Shia population. It appears Solemeini not only felt justified in being the likely mastermind behind Tuesday's attack on the U.S. embassy in Baghdad, he also was comfortable enough to travel to Iraq personally to oversee it. But this time, he got too comfortable. We're already hearing from a number of critics that this move will likely backfire against the U.S. and will provoke Iran to retaliate even more forcibly against American and its allies. To those people making those warnings, there's really only one thing to say: "Welcome to the party, pal!" That's because Iran has really been at war with the U.S. since 1979. The killing of hundreds of our troops in Iraq, the constant terrorism it sponsors and supplies against Israel, and even the recent provocations against oil traffic in the Persian Gulf are all acts of war from which there really is no retreat without severe consequences. For the Trump administration, it would appear the embassy attack was the last straw. It was also one that provided the ultimate opportunity to eliminate Soleimani as he foolishly left his home country and made himself more physically and legally vulnerable. Another thing to remember is that Soleimani and his foreign escapades may have been the delight of the ruling mullahs in Tehran. But the people in the streets abandoned him long ago, if they ever really supported him in the first place.
