The Saudis, western media and governments all tried to tell us how the Houthis weren't sophisticated enough to carry out the drone/missile attack a few weeks back, despite headlines like these in May.

The Houthis have since raised it to another level.
In a three day battle the Houthis invaded and occupied more than 350 kilometers of Saudi territory, while destroying three Saudi brigades.

Yemen's Houthi rebels on Sunday broadcast footage they said was of a major attack on Saudi Arabia in August that killed or wounded 500 soldiers with thousands of others surrendering.

Yahya Saree, a Houthi military spokesman, described an ambush on the Saudi forces that then developed into an "all-out" cross-border offensive that trapped the troops inside Saudi Arabia.

"More than 200 were killed in dozens of [missile and drone] strikes while trying to escape or surrender," Saree said.

Catherine Shakdam from the Next Century Foundation told Al Jazeera there was no reason to doubt what the Houthis are saying.

"The video and images coming through are actually affirming the statement. It's a pivotal point in this war that now Yemeni are moving on Saudi land. It's quite interesting to see with all the talk of a grand Saudi coalition that Saudi is very much alone in this fight," Shakdam said.

The Houthi offensive was actually carefully planned and coordinated.
The Saudi troops were lured into the killing zone.
As the trap was sprung, Yemeni rocket artillery targeting Jizan airport, denying the possibility of air support for the encircled troops. The Houthis also hit the King Khalid International Airport in Riyadh targeting Apache helicopters, and nearby military bases so as disrupt the chain of command.

When the Saudis first invaded Yemen in 2015, it was thought that the war would only last a few months. The Saudi military budget is almost 90 billion dollars a year, and it has the most advanced U.S.-made weapons.

Yemen has turned into Saudi Arabia’s Vietnam. Ditto for the UAE. The two countries have sunk billions of dollars and countless troops and mercenaries into what has become a quagmire of catastrophic proportions.

A nation with one of the largest military budgets is a) incapable of defeating one of the poorest nations on the planet, b) is incapable of defending its own borders, and c) is incapable of protecting its critical infrastructure.

This is a big deal.

Not just to the Saudis, but to the U.S. as well.
Washington not only backs a totalitarian government that funds anti-American terrorist groups while committing genocide. Washington is also standing behind a government in the process of losing a war just as it has antagonized many of its neighbors, meaning that we are standing on the wrong side of a power struggle.
