I don’t believe he was killed al kiddush Hashem. He wasn’t killed because he was jewish OR because of mitzvos. He was killed because of his political plans to expel millions of arabs from their jomes. He knew exactly the ire and violence that would come in its wake, and took on the mantle of warrior. He was fighting a nationalistic war, not a religious one. His killing was one militant killing another who was threatening his people’s right to live in their homes.
Why is that dying al kidush Hashem? It’s more like dying al kiddush ha-nationalism.
