...one respected group puts its rough estimate at closer to 50,000...

In the words of the great Palestinian poet Mahmud Dawlish:

Our Country is a Graveyard

Gentlemen, you have transformed
our country into a graveyard
You have planted bullets in our heads,
and organized massacres
Gentlemen, nothing passes like that
without account
All that you have done
to our people is
registered in notebooks

...so even taking that "reassuring" best-best-best-case estimate of 50,000 dead Iraqis, after deducting roughly-3000 US military deaths plus probable later deaths of severely wounded soldiers...AND a further roughly-3000 deaths for 9/11 plus firemen's cancer-deaths etc... despite the fact that Iraq and Iraqis had zero-zilch to do with all that, from an ME "lex talionis" standpoint the US (and/or "the West") now owes Iraq (and/or "the Muslim world") well over 40,000 lives.
