Honestly speaking? I think it would be a solid gesture of support... had it followed the Israeli government doing something on the scale of shifting it's policy on the people in (East)Jerusalem from "You may apply for citizenship, we may process the application at our leisure or shred it on a whim."* to "All residents of Israel's Indivisible Capital are citizens by default. Here are your new IDs, Arabic-language voting materials, the paperwork needed to opt out in the name of Arab Solidarity(tm) if you are dead set on that." Too bad Bibi is too busy lining his pockets and sucking up the the Barking Mad Right for him to make such a move.
(*: Mind you, I do call the lack of around-the-block lines at the applicable offices painfully shortsighted at best.)
As it stands? Pointless gesture until a peace agreement is signed.
