Iran has had an impressive run for the past decade _ expanding its regional muscle through proxy militias, its expanding missile capabilities and its big brother role with Iraq's Shiites after the toppling of arch-foe Saddam Hussein. But the fallout from the post-election unrest will most likely bring tougher times for Iran's ambitions beyond its borders. Beside Iraq, the Iranian-backed Hezbollah would be the group affected the most by who wins Iran's ongoing confrontation. AP Photo logo AP Photo 32 months ago
