It’s been known for a while that some Arabs were enthusiastic about Hitler, but your article doesn’t prove that they planned their revolt for Hitler’s birthday.
In the 1990s some people were quick to claim that the Oklahoma City bombing and the Columbine high school shootings were scheduled to happen because of Hitler’s birthday. That’s been disputed. It hasn’t been proven, but it can’t be entirely disproven. It remains speculation.
I understand, but Haviv Kanaan wrote it on the basis of signs he saw as a policeman in the area. The Arabs who attended the birthday celebration by the Templars also reinforced this in his assertion. .
