Iran's top ruler has promised to "punch" the Western powers this week in a way that will "leave them stunned."
This Thursday marks the 31st anniversary of Iran's Islamic Revolution, and the threats are building as the date grows closer.
In addition to Ayatollah Khamanei's threats against the U.S., Britain, and Israel, Iran also announced it will boost its enrichment of uranium to 20 percent, which is up from the three to four percent it currently produces.
Iran's President Mahmoud Ahmadinejad is warning the West it cannot make weapons systems that can stop Iran's missiles.
Despite all the bluster from Tehran, reaction in the U.S., Europe, and Israel has so far been subdued.
"If Iran continues and develops nuclear weapons, it almost certainly will provoke nuclear proliferation in the Middle East. This is a huge danger," Secretary of Defense Robert Gates said.
Gates has been meeting with French leaders, trying to get world powers to agree on tough sanctions against Iran. He said he still believes there is time for sanctions to work.
The International Atomic Energy Agency forecast last year that Iran could have two nuclear bombs by this month.
That doesn't leave much time for Israel's Prime Minister Benjamin Netanyahu who called for immediate "crippling" sanctions on Iran, based on its decision to further enrich uranium. Israel has said it will not allow Iran to cross the nuclear threshold.
Meanwhile, on "Fox News Sunday," former Vice Presidential candidate Sarah Palin answered a question about the 2012 Presidential race by suggesting an attack on Iran could change Obama's political fortunes.
"Say he decided to declare war on Iran or decided to really come out and do whatever he could to support Israel, which I would like him to do, but that changes the dynamics in what we can assume will happen in between three years, because if the election were held today, I do not think Obama would be elected," Palin said.
Now that the President's year of dialogue with Iran is over, the next step will require him to get tougher, and the Mullahs in Tehran seem to be daring him to do it.
