Which Is It?

In last week's Presidential debate, George Bush said:

We've already sanctioned Iran. We can't sanction them any more.

In last night's Vice-Presidential debate, Dick Cheney said:

We've got sanctions on Iran now. We may well want to go to the U.N. Security Council and ask for even tougher sanctions if they don't live up to their obligations under the initial -- International Atomic Energy Agency Non-Proliferation Treaty.
