The futility of negotiations with Iran's religious bigots

Daily Caller:

Iran’s supreme leader, Ayatollah Ali Khamenei, all but said on Sunday that negotiations over the country’s illicit nuclear program are over and that the Islamic Republic’s ideals include destroying America.

“Those (Iranians) who want to promote negotiation and surrender to the oppressors and blame the Islamic Republic as a warmonger in reality commit treason,” Khamenei told a meeting of members of parliament, according to the regime’s Fars News Agency.

Khamenei emphasized that without a combative mindset, the regime cannot reach its higher Islamic role against the “oppressors’ front.”

“The reason for continuation of this battle is not the warmongering of the Islamic Republic. Logic and reason command that for Iran, in order to pass through a region full of pirates, needs to arm itself and must have the capability to defend itself,” he said.

“Today’s world is full of thieves and plunderers of human honor, dignity and morality who are equipped with knowledge, wealth and power, and under the pretence of humanity easily commit crimes and betray human ideals and start wars in different parts of the world.”

In response to a question by a parliamentarian on how long this battle will continue, Khamenei said,“Battle and jihad are endless because evil and its front continue to exist. … This battle will only end when the society can get rid of the oppressors’ front with America at the head of it, which has expanded its claws on human mind, body and thought. … This requires a difficult and lengthy struggle and need for great strides.”

What I don't understand is why the Obama administration refuses to take this guy at his word.  We need to be prepared to resist Iranian aggression aimed at the US and its allies.  All Obama and Kerry are doing is giving them the gift of time to pursue their objectives.
