This is similar to my musings while discussing it with my workout buddy this morning as it was on the news. My understanding from each of Trump and Netanyahu's meetings is that Bibi leaves the meeting unhappy, so when I saw the news I stated that Trump is extracting concessions from Bibi with this announcement (whether it was negotiations in real-time or not).

I'm not getting my hopes up, but agree that it could undercut Israeli aims at territorial seizure and provide the (non-militarized) Palestinians with a means to stay in their homeland. Could, but we're inserting our own hopes and vision onto another man's actions. We'll have to see what he ultimately does.
