Huh? I am fairly certain that fiscal union was always the plan, not achievable politically, so left for later introduction when it became obviously necessary.

Anyway, I don't buy that it's Germany that's blocking. Of course, fiscal union means giving up a good chunk of sovereignty, which is where many of the member states balk. Fiscal union is OK if it means we get money, not so OK if we are no longer allowed to spend any way we want.
