Lebanon is holding crucial parliamentary elections this Sunday.

Voters will decide between the Iranian and Syrian-backed Hezbollah party and a Sunni-led coalition that is supported by the United States.

Polls show that Hezbollah, considered a terrorist organization by Washington, has a pretty good chance of winning the vote.

Experts say that a Hezbollah victory would pose a major problem for the Obama administration.

The U.S. plans to suspend military aid to Lebanon if Hezbollah and its allies win Sunday's elections.
