What's the goal again?

I keep wondering one thing with this Israel-Hezbollah conflict:

What's the latest update with the kidnapped Israeli soldier?

Supposedly this entire thing started 'cause an Israeli soldier was kidnapped and was going to be shuttled around to different Arab states. "Don't leave a man behind!" motto is something I can kinda understand, so fine. But after the first 48 hours, I haven't heard squat about this guy's condition, location or attempts to find him. For all we know, Israel could have put him under 30 ft of rubble in Lebanon.

This kinda reminds me of Iraq - "Where's Osama? We want him! Quick - take out Iraq at all costs!!!!". Or that South Park episode:

"We gnomes are going to be rich. Here's our plan:
Step 1: steal underpants
Step 2: ???
Step 3: make profit"

WTF?! Am I missing something here?!
