The Reprise of WMD's?

I'm late to the game to comment on the Israeli / Hezbollah war. It's been going on for 8 days now and the obvious things have already been said:

- Hezbollah in the North, and Hamas in the South, provoked the war with their illegal kidnappings of soldiers and with sustained rocket attacks into Israel
- Israel has a right to defend itself
- Isreal's defense does not have to be a "proportional response" to just the kidnappings, anymore than the U.S.'s response to 9/11 was just going after the small group of al Qaida that planned the attack. You have to keep going until the group that threatens you is crushed and can't attack again

All that's been said.

My worry, beyond whether this war will escalate and drag us all in, is this:

If Iraq had WMD's before our invasion, which I believe they did

and if Iraq moved those WMD's before we arrived, which I believe they did

and if Iraq moved those WMD's into Syria, or worse as some evidence indicates through Syria into Lebanon, which I believe they did

how soon until those WMD's get unburied from the Bekaa Valley and used against Israel?

That would not be good.
