It's possible to respect the abilities of someone you consider evil. You should always give your enemies as much respect as they are due. Otherwise you underestimate them.

Iran does not want chaos. A smaller power with a more powerful enemy rarely wants chaos. Nation States never do. They are inherently conservative in that aspect for obvious reasons.

Holding a city doesn't make you a faction. It means that Ansarallah recognized that winning outright would require fighting their own people, and so they stopped when they did and switched to diplomacy. This is like saying the US has 8 (or however many, I'm not looking it up) political parties. It's not wrong, but there are only 2 that have any power and saying otherwise would be a lie.

Don't whine about someone calling your opinions stupid when they corrected you without insults and you responded with insults. Stupid insults.
