A former director of the Central Intelligence Agency says a military strike against Iran is becoming more likely.
Michael Hayden, the CIA's top spy under President Bush from 2006 to 2009, told CNN military action may soon be the only option.
Hayden said that no matter what demands the U.S. makes, Iran will continue to move forward with their suspected nuclear program.
"We engage. They continue to move forward,'' Hayden said. "We vote for sanctions. They continue to move forward. We try to deter, to dissuade. They continue to move forward.''
The former CIA chief joined a growing number of analysts who think a military strike could happen in the near future.
U.S. officials have said military action remains an option if sanctions fail to deter Iran. The United Nations Security Council has passed four sets of sanctions over Iran's nuclear program on the suspicion that it is being used to produce weapons.
Iran has continued to deny the accusations, responding that the Islamic Republic is using its nuclear technology for peaceful projects, like the generation of cheap electric power.
