Political insight as an extremely important factor

I have repeatedly said this in cases regarding Islamic history that the
thing that led to the defeat of Imam Hasan (pbuh) was the lack of
people’s political insight. People weren’t able to analyze politics.
That which caused the Kharijite sedition and put Imam Ali (pbuh) under
such pressure, that which oppressed the most powerful person in history
in that manner, was the lack of political analysis among the people.
Otherwise, not everyone was irreligious. They couldn’t analyze politics.
The enemy would start a rumor, this rumor would immediately spread
everywhere, and people would accept it!
