On Saturday, October 7, 2023, the Palestinian Hamas organization carried out an offensive crossing the Gaza Strip's contractual border, muslim troops reached Ashkelon and Ofaki, taking over half of Israel's defence Forces Bases – Cahal (IDF). Hamas committed crimes on civilians, kidnapped people, killed children, and abused women. The scale of the attack was a shock not only to Israeli public opinion but turned the world's eyes to the mediate East. In today's planet Army cycle, I would like to explain to you what Hamas is and what the way from the position of the independency opposition movement to the extremist jihadist doctrine has passed by armed Palestinian groups.
