the western world is becoming increasingly adamant about a palestinian state that includes east jerusalem...and the u.s. veto in the unsc is growing weaker as it's allies become more apt to vote independently of its wishes; and that's IF it chooses to exercise it. it can just as easily withold its vote altogether. israel's steadfast refusal to respect those boundaries recognized by the u.n. and the international community, is taking it ever closer to possible sanctions...or even a mandated settlement of boundaries in which it stands to lose any bargaining power it might now have over retaining larger settlement blocks... and in jerusalem particularly, there's not likely to ever be an option for retaining its enclaves with territorial exchanges. israel is underestimating the growing resolve over this issue among the western nations.
