welllllllllllllllllll, given that Holland, like New Orleans, is below sea level and, after especially bad flooding in '53 had to rebuild levees and dams that have protected the country ever since, it makes sense their Ambassador would be in LA, as they are going to have to do what Holland did.
A much smaller "botique new orleans" could be left. Most of the good land is where (surprise!) the good buildings are. Many of the high rises were not flooded.
I don't see why US Taxpayers should pay to rebuild below sea level slum housing, or replace it with anything more ambitious than .. a golf course.
