Well, you read at the end that that there were items in storage due to the dangers of war. Hopefully and presumably these were the most important items.
Of course the criminals are the looters, not us, but it is still, as said above, unfortunate. If there are one or two other museums like this in the country, or if there are parts of this museum they didn't get to, I would think each museum would be worth, if not a tank, at least a Bradley.
That's an important point ---the Iraqis themselves are the ones destroying their museum. It might even look bad if we killed any Iraqis in trying to protect their history and culture for them.
