At some point

someone is going to have to call them on shit like this...
in my opinion, right after your new government decides on a foreign minister who's responsible for quotes like this '...the Israeli daily Haaretz reported that Lieberman called for thousands of Palestinian prisoners held by Israel to be drowned in the Dead Sea and offered to provide the buses to take them there' might be a good time.

Of course, it's hard for us to exert any moral authority thanks to the last 8 years - but we should probably try anyway.
