Judy Woodruff:

Now, this week marks seven years of Syria's civil war.

What began as an uprising against the regime of Bashar al-Assad has become a regional proxy war. And one of the main combatants supporting Assad is Hezbollah, the Lebanese Shiite militant group. Its operations in Syria, its relationship with Iran, and its power in Lebanon are a constant concern of Israel.

And now there is talk of another Hezbollah-Israel war in the offing.

With me now for more on this tinderbox is special correspondent Jane Ferguson, whom we have the pleasure of hosting here in studio. She's on a visit from her home base in Beirut.

Jane, it's so good to have you with us.

And there has been more talk recently of a possible war between Israel and Hezbollah. What does it look like?
