Hamas has learned that lesson well.
On Hamas' Arabic webpage, there is a press release and an article about the 103rd anniversary of the Balfour Declaration.
In both those cases, Hamas emphasizes that "armed resistance" (i.e., terrorism) is a valid option: "Resistance in all its forms, from popular to armed, will remain a legitimate and proven option, and it will not be withdrawn to restore the stolen right of our people and sweep the occupation."
But in its English language website, there are no articles on Balfour. The only article about "resistance" is a copy of a Mondoweiss piece about hunger striking as a form of resistance.
Even terror groups try to pretend to be peaceful when appealing to their Western fans.
