I fully understand your position. I am not attempting to criticize or refute it.
Let me offer you a parallel example:
Currently, there is an intense struggle between China and the Philippines in the South China Sea. (I am not sure if you are aware of this situation.) Suppose, at this moment, Russia were to say to China: "I will send my naval fleet to the South China Sea to support you."
How do you think China would respond?
I can tell you quite clearly: China would have only one response for Russia—"Get out!"
The conflict between Saudi Arabia and the Houthis actually bears many similarities to the situation between China and the Philippines—in both cases, a powerful entity is facing off against a much weaker one. Yet, look at how Saudi Arabia has responded: not only did it invoke the MDA agreement to seek help from Pakistan and Turkey, but other nations—such as Egypt and the United Kingdom—also stepped in to assist. And, of course, there is the fact that Saudi Arabia even requested support from the United States...
And you expect me to believe that Saudi Arabia is an exceptionally powerful entity?
Do you realize how ridiculous that is?
