I think its symbolic, but coming so late in the Obama administration and with such a pro-Israeli president about to be inaugurated it'll mean very little.

I do slightly disagree with the above assessment though, if Israeli got a similar treatment to the one Apartheid South Africa got then they would be forced to relent as so many voters would lose out financially. There may be enough support to keep the settlements going when it doesn't really cost Israeli's that much but if they started taking big financial hits then that support might disappear quite quickly.
