There's been a theme this week. On Thursday, the U.S. carried out a deadly drone strike against a militia group in Baghdad. A day earlier, the U.S. threatened tougher action against Houthi rebels in Yemen. And on Tuesday, a Hamas leader was killed in a drone strike in Beirut.
The thread that ties these events together is Iran and its proxies. All these attacks or warnings are directed at Iran's broad network of militant groups that are spread across the Middle East.
