Here's a Chinese saying for you: "光脚的,不怕穿鞋的(Those who are barefoot have nothing to fear from those wearing shoes)."
The Houthi rebels originally had nothing. They have nothing left to lose.
But Saudi Arabia is completely different.
As the war continues to escalate and Saudi Arabia drives the Houthi forces into a corner, they will begin to act without restraint. That is when a truly "brutal war" will begin!
Is Saudi Arabia mentally prepared for this? ------ The Houthi rebels wouldn't care if all of Yemen were reduced to scorched earth. But if Riyadh were also reduced to scorched earth—would Saudi Arabia care then?
How do major powers respond to guerrilla warfare waged by weaker nations or organizations? Clearly, none of the three MDA countries have learned this problem.
