Iran on Nuclear Weapons

E-mail to Congress:

EIN News says, "Obama Issues Ultimatum to Iran to Open Secret Uranium Plant to UN Inspection. Barack Obama has issued a strongly worded ultimatum to Iran after it admitted having a secret uranium plant that was revealed earlier today by US officials. Obama demanded UN's International Atomic Energy Agency (IAEA) be allowed access to the secret site, which according to US officials is built inside a mountain near the ancient city of Qom, one of the holiest Shia cities in the Middle East.

An ultimatum means, "You must do this, or I will----. I don't see any of the "or I will----" in the above statement. Therefore, it is a hollow remark.
I have no particular suggestion on how to handle Iran, but I have a comment on what Pres. Obama said to the United Nations. In essence, he said we are going to ban atomic weapons from use in the world. This is in the same category as banning sin, fraud, prostitution, drug use, etc.. It can't be done. When will this president confront reality?
My only hope is that Congress has more common sense.
