Obama was forced to use the veto because he has en election slowly creeping up on him and he needs the pro Israel voters. From the first day he took office Obama has gone out of his way to make the US an enemy of Israel and friend of the islamic world and if Obama is going to pick up those pro Israel votes he needs to reinvent himself as being much more Israel friendly and that means using the veto. Nothing makes the government less friendly amongst US pro Israel voters than America allowing the UN to pass a resolution condemning Israel. Americans do not have the great love of the UN Obama does. I think most Israeli's understand how the UN feels about settlements, we have scored our victory in Obama being forced to veto the resolution now though it not the time for senior cabinet members to be boasting and saying the UN is pro settlement.
