FNA- Secretary of Iran's Expediency Council (EC) Mohsen Rezayee underlined that Tehran is not concerned about US President-elect Donald Trump's choices for the CIA chief and secretary of defense as the American Generals understand Iran's capabilities better than politicians.

"We are not concerned to see that Generals hold Mr. Trump's cabinet posts. They are wiser than many of the US politicians. We are well aware of their record, level of understanding and knowledge and they are also fully aware of our capabilities," Rezayee, the former commander of the Islamic Revolution Guards Corps (IRGC), wrote on his Instagram page on Saturday.

"They understand well that Iran is a patient lion and watchful tiger that they shouldn�t approach," he underscored.

His remarks came after Trump introduced retired Marine General James Mattis to lead the Pentagon and Republican Congressman Mike Pompeo for the CIA chief post.

Mattis is a four-star military officer who enlisted in the Marine Corps in 1969. As senior commander, Mattis distinguished himself in combat in the country�s wars in Iraq and Afghanistan, although some critics are concerned that he falls short of the diplomatic experience expected for the position. Nicknamed �Mad Dog,� Mattis is also known for his glib remarks, including an instance in 2005 when he said it was��fun to shoot some people�.

Pompeo was on the House Select Benghazi Committee that investigated the 2012 attack that led to the deaths of US Ambassador Chris Stevens and three other Americans. He has also been a�vocal opponent�of the Iran nuclear deal and favors reinstating the National Security Agency�s�bulk collection of phone metadata, a program exposed by former NSA contractor Edward Snowden in 2013.
