At least European elected leaders are a lot more diverse in thought, when it comes to Israel/Palestine. We have both governments that basically take the US line and would probably enact the same policies, but we also do have politicians in power that are willing to stand up and speak out. That does provide a little bit of hope. One big difference between the US and Europe on this topic seems to be that Europe doesn't have anywhere near as much of the religious fundamentalism that leads to dogmatic support of Israel.
That might change as Europe continues to drift towards right wing populism. You know things are taking a turn towards the worst when even in Portugal they are consistently growing.
