Chris Matthews: Iran will remember what the United States did

On the assassination of Qasem Soleimani, Chris says “Assassination is not a method for ending belligerence with a foreign power; it's a way to deepen it. By ordering the killing of this Iranian general we have unleashed something. It will not end with the Iranian firing of those ballistic missiles into the Al Assad military base. The Iranian people are going to remember it for years.”
