The Obama Administration is reportedly considering sanctions against Israel over the construction of settlements in Jerusalem.
It's not like these settlements would end up being part of a future Palestinian state . None of that matters. This is about sticking it to Israel.
This is the same Obama Administration that is actively opposing any further sanctions against Iran in the vain hope of obtaining a nuclear agreement.
However, I don't expect the Obama Administration to embark upon any sanctions until after Israel's elections in March. If the Obama Administration were to do that then Israeli voters would close ranks around Netanyahu. The last thing Obama wants is a strong Bibi.
