It would be the first time the United States has placed the armed forces of a sovereign government on its list of terrorist organizations.
The question is: Why this possible move, and why now?
Tensions between Washington and Tehran have been rising in recent months, with the administration of U.S. President George W. Bush accusing Iran of arming militants in Iraq and Afghanistan as well as secretly pursuing a nuclear weapons program.
Iran denies the charges.
'There Will Be Consequences'
Bush, speaking last week in Washington, raised the stakes himself, saying there would be “a price to pay” for Iran’s alleged smuggling of weapons to Iraq.
"One of the main reasons that I asked [U.S.] Ambassador [to Iraq Ryan] Crocker to meet with Iranians inside Iraq," Bush said, "was to send the message that there will be consequences for people transporting, delivering [explosively formed penetrators], highly sophisticated [improvised explosive devices] that kill Americans in Iraq."
Now, the United States looks set to take an even more aggressive approach to Iran.
According to U.S. media reports, citing unidentified administration officials, a decision has been made in principle to name elements of the corps a "specially designated global terrorist" group. That designation was created by Bush in 2001 as part of larger measures to cut off funding for extremists.
The move would allow the United States to block the guards' financial accounts and other assets.
Power Base For Ahmadinejad
The Revolutionary Guards Corps dates to the Islamic Revolution of 1979. Its branches reportedly extend widely throughout the Iranian military, and some estimates put the total number of guards forces at round 125,000. The corps is seen as being a power base for Iran’s hard-line President Mahmud Ahmadinejad.
Ahmadinejad himself was a member of the guards during the Iran-Iraq War in the 1980s.
But why move against it now?
According to "The New York Times,” Washington could have several motives.
The United States is reportedly concerned about delays in efforts to win approval from the UN Security Council for further economic and diplomatic sanctions on Iran. Reports say the administration may feel it has little choice but to take unilateral action.
More Muscular Approach
In that sense, putting the Revolutionary Guards on the foreign terrorist list could further press Washington's European allies to back stronger sanctions against Iran. There is also talk that the move could help satisfy U.S. “hawks,” such as Vice President Dick Cheney, who have been calling for a more muscular approach to Iran.
But the designation itself could also prove to be a significant financial blow to the military group.
