Yes. They killed Yassir Arafat. They also killed Shaik Yassin. They killed Haniyeh, they killed also Nasrallah and even al-Ghamari. And many many others ...at night, poisoned, by the back or from the air.
They will kill tens more of resistants. But that doesn't give the victory to them. Palestine Resistance are not based on individuals. Hizbollah and also Houthi movement are not based in personalist cults.
So, if you think that they won because those limited success you don't understand the long game of Resistance.
Just see the face of Netanyahu when he says any of his usual nonsense or desperated lies. See how israelis are fleeing of their own country, using their shameful european or american passports while hidding their real nationality.
Maybe you can hide or just diminish the success of Islamic Republic against the Hegemon allied with Israel, but you can't say that the bitter face of those zionists scum and their supporters are simulated or showing satistaction.
Ironically even Keir Starmer are to fall before Islamic Republic. And many more will if Irán persists.
With our without your support.
Sorry to read your defeatism.
