Raze that building in NYC to the ground. Sell the land for honest, value producing, commercial development.
The only thing the UN offers of value is our Security Council veto right.
We could ask the UK or France to use their veto.
Israel has about 350 possible vetos of its own I believe.
I believe the Rockefellers bought the land and gave it to the UN.
It would fetch a handsome price nowadays.
