Life is not a video game. The US and Saudi Arabia already spent 7 years trying to level Yemen to stop them from firing cruise missiles everywhere in the region, and failed. The US didn't managed to stop Iraq from launching ballistic missiles until over a year after the decision to invade was made, and now look at Iraq right now, various militias are still firing missiles at US military bases and getting away with it. Yemen is just a proxy of Iran, ultimately, and the US has already lost multiple proxy wars against Iran. Invading Iran itself is not a workable proposition, either.
