Am I understanding the concept of "Revolution" correctly?

Their goal is to establish Islamic states where religion and politics are unified (theocracy).
They are a transnational organization aiming to turn all Muslim-majority countries into such theocratic Islamic states.
Iran is the country that has successfully achieved this.
Applying this to all Arab nations is what they call a "Revolution," and the Revolutionary Guard is the entity that protects those values...
Is this why the remaining Arab monarchies dislike, check, and fight against Iran—or more specifically, the Revolutionary Guard?
As for the Houthi rebels this time? Even if they are named the "Houthi rebels," aren't they essentially just another Revolutionary Guard?
