It’s a fucked up situation, but until enough of the voterbase is convinced or he no longer has to worry about the election, he’s in an awful bind.
The unpleasant truth is that, to some extent, the US is still a democracy, and the opinion of the people matters. If the majority of the US populace doesn’t see it as genocide, it is democratically right for him to act on that opinion.
Which means the fault isn’t with him alone - arguably, he could take the risk and attempt to inform people - but also with the voters, the propaganda that misled them and the fucked up election system.
