Houthi attacks have dropped in recent weeks due to U.S. airstrikes. Because the attacks are not as frequent as three months ago I am assuming that that it will happen, albeit not as quickly as we would like.
The U.S. has to be careful to avoid civilian deaths, aka collateral damage, otherwise they will be accused of committing some type of "atrocity," similar to what Israel is facing. The Saudis had that problem. What a screwed up world we live in. I say if you are going to fight a war, fight to win.
