Answer
The US military was severely impacted by Mughniyeh's alleged activities. Mughniyeh was responsible for the 1983 Beirut barracks bombing, which killed 241 US Marines and sailors. He was also accused of being involved in the 1996 Khobar Towers bombing, which killed 19 US airmen. These attacks caused the US to increase its military presence in the Middle East and to launch a series of airstrikes against Hezbollah and its allies.
