Don't piss off the already-pissed-off Muslims. Whatever you do, don't make them start committing acts of terror.....oh, wait.
The topic isn't Islam per se, the topic is Jerusalem and there is a reason why Jerusalem was declared an Open City ie. meaning it's for EVERYONE Christians, Jews and Muslims.
Jerusalem is the powder keg of the world and that's why it's been treated with such delicacy and considered Neutral Territory and just because America might put their embassy there means nothing, America is only ONE nation out of I think it's now 196 nations and I guarantee not many more nations are going to follow America and start putting embassies in Jerusalem, so in the scheme of things it's a pointless exercise, it has only some Symbolism but that's all, it means nothing.
