Why did the United States only send a Patriot missile launcher to help Saudi Arabia?

Because Saudi Arabia is like a helpless pig teammate, no matter how powerful and perfect the military equipment is, it is a bunch of useless weapons in Saudi hands. Because Saudi Arabia is a bunch of veterans, the army can't attract it, and even the most advanced weapons in the world can't help Saudi Arabia. The reason why the United States only shot Patriot missile launchers to help Saudi Arabia was out of humanitarian help.

Saudi Arabia accused the Houthi armed forces of launching ballistic missiles and vowed to destroy the missile launching capability of the Houthi armed forces. This seems to imply from another angle that Saudi Arabia admits that Houthi armed forces have ballistic missile technology. In other words, the previous attack on Saudi oil facilities may really have been done by Houthi. After the incident at that time, the Houthi armed forces had declared responsibility. However, the United States, Britain, France, Germany and other countries identified Iran, and Saudi Arabia also targeted Iran.

If Houthi's statement is finally proved to be true, it means two things. One is that the Houthi armed forces won a total victory, and more than 1000 Saudi soldiers surrendered. This is undoubtedly a heavy blow to Riyadh, and it will also make the face of the United States have nowhere to put, because Saudi Arabia is an ally and financial master of the United States, and the United States has been providing strong military support to Saudi Arabia. The Saudi army supported by the United States can't beat the Houthi armed forces, and the United States naturally has no face.

In order to prevent Saudi Arabia from being attacked again, the United States recently announced a specific plan to send more troops. The Pentagon will send 200 American soldiers, a Patriot missile system and four sentry radars to Saudi Arabia. This is a support for allies, but the performance of Saudi Patriot air defense missile system has long been a joke. Putin suggested that Saudi Arabia switch to Russian air defense equipment, while Iran even laughed at the humiliation of American air defense equipment. Under this circumstance, it seems only symbolic that the United States also sent the Patriot air defense missile system to Saudi Arabia.
