In a television interview, Obama also said he did not believe Tehran had the "intentions or capabilities" to attack the United States, playing down the threats from Tehran and saying he wanted a diplomatic end to the nuclear standoff."Any kind of additional military activity inside the Gulf is disruptive and has a big effect on us. It could have a big effect on oil prices. We've still got troops in Afghanistan, which borders Iran. And so our preferred solution here is diplomatic," Obama said.His comments echoed concerns expressed by earlier by Iran's neighbor Turkey that an attack on Iran would be disastrous."My number one priority continues to be the security of the United States, but also the security of Israel, and we are going to make sure that we work in lockstep as we proceed to try to solve this, hopefully diplomatically," he told NBC. The former Air Force commander also criticized the US and Israeli security and political establishments for "talking too much" about a possible strike on Iran."The fact that senior officials in the security establishment drop fragments of information every once in a while is irresponsible," Halutz said in an interview with Army Radio on Monday.
