ABC News' Kirit Radia reports: Secretary of State Hillary Clinton will deliver what her aides are touting as a "major" foreign policy address this afternoon, a day before she leaves on her first foreign trip since breaking her elbow in a fall last month. Some view the speech as Clinton's attempt to "elbow" her way back into the administration's foreign policy limelight. The injury sidelined her for much of the past month, causing her to cancel trips and meetings and miss President Obama's recent trip to Russia, Italy, and Ghana. The speech is likely to focus on the "big picture" foreign policy approach, according to State Department officials. According to excerpts of her remarks provided this morning, Clinton will hold the door open for talks with Iran despite Tehran's crackdown on political protestors following last month's election. But, she will warn Iran the offer will not be on the table for ever. Clinton will call the political crackdown in Iran "deplorable and unacceptable" but adds that "We remain ready to engage with Iran." "The opportunity will not remain open indefinitely," Clinton will say, though the excerpts do not define how long the Obama administration will keep its hand extended to Iran.
