We can assume this will be far more costly.
To put it in perspective, the bullet has been fired at New Orleans. It's not a matter of dodging it anymore. It's about whether it's going to hit the heart or just the chest.
If it's a heart shot, what's the value, in billions, on moderately sized American city?
I don't think there's any frame of reference for this. The Port of New Orleans and the Oil/Gas infrastructure alone has got to be representative of tens if not hundreds of billions of dollars alone. Throw in all the historic artifacts - the town was integral to the Spanish, French and British inroads to the New World and was also a central area in the Confederacy (not trying to go down a political road with that last one - but no matter your thoughts on the matter a great deal of history from that period is at risk).
Add in a few more billion for the downtown area and likely hundreds of billions for the surrounding areas of Metaire, Lakeview, Kenner, St Bernard and Plaquemines. I'm emotionally numb as I consider the possibility of all the places and things that were integral to my entire childhood and young adult life being washed away.
