Yet Al-Jazeera recognizes Al Qassam for what they are... Hamas' military.
What is Hamas’s armed wing, the Qassam Brigades?
Gaza-based Qassam Brigades has been waging an armed resistance against Israeli occupation since its founding in 1992.

Nope. You've made two claims: Al Qassam isn't Hamas' military arm and that Sinwar had no idea that October 7th was happening.
You need to support your claims because both are directly contrary to what is reported and believed to be accurate.
So, again, what is your source for both?
