Houthi are a force to be reckoned with impressive capacity to challenge advanced armies. Houthi
have underground military facilities and make extensive use of drones, cruise missiles, and ballistic missiles to produce significant battlefield effects. Kamikaze drones can be mass produced at much lower costs and have changed the calculus on many levels. Houthi receive important supplies from
Iran and
Russia and have created domestic industry to manufacture weapons (see
this and
this). The US might have to change its strategy to defeat Houthi in war as mentioned
here. Nevertheless, modern societies are very complex and war in this age cannot be won overnight. Some think that war is like a video game but it isn't.
There is no such thing as a 1000 times more terrifying missile power than Houthis even on paper. If this was true than Iran would have bombed Israel back to the stone age but read
this,
this, and
this. Not that I underestimate Iran and its capacity to attack regional powers and anti-shipping capability but a state-based power also has more visible infrastructure than a force like Houthi and weaknesses that can be easier to exploit accordingly. Iran created several layers of defense with its Axis of Resistance strategy but a chunk of it has collapsed in war lately. Let's see what happens next.
