Sanctions on Iran?

The UN Security Council is to meet tomorrow to impose sanctions on Iran for its adherence to its nuclear program. After many months of diplomacy, it seems that tomorrow an agreed upon resolution will pass. This resolution shall include a series of "soft" sanctions on Iran.
The United States, which has led the campaign to impose sanctions, deisred stronger measures, but wishing to arrive at a consensus among the permanent members of the council led to the adoption of a much softer draft.
At the last moment it seemed that Russia may in fact be reluctant to go through with the sanctions at all. President Putin is to review the final draft and to confirm it personally. In Israel there is grave concern that Russia may impose an even softer batch of sanctions which are unlikely to cause the Iranian program any tangible harm.
The current draft of sanctions includes a list of products that should be denied the Iranians and another list of persons and organizations which work in conjunction with the Iranian program, which should also be denied right of purchase of products and materials which may be used to further the Iranian program.
