President Obama is “simply not serious” about nuclear negotiations with Iran and “the Iranians know it,” Charles Krauthammer said Friday following Tehran’s announcement of a new generation of equipment to enrich uranium.

“The only surprising thing here is that the Iranians are so confident about how supine Obama is on this that they stick a finger in his eye and announce it publicly,” Krauthammer said on “Special Report with Bret Baier.”

The syndicated columnist and Fox News contributor said that as for Iran’s six-month nuclear deal with the U.S. and other world powers, “there is nothing in the agreement that stops the Iranians from enriching more uranium and producing the machines that enrich the uranium. That was the problem at the beginning. That's what made the agreement a farce at the start.

“Unless you go after the uranium enrichment, unless you curtail or destroy the machines that enrich the uranium, you have done nothing to stop the progress of Iran,” he said.
