Why does the U.S. need to belong or support and organization which consistently votes against the U.S. and it’s interest?
Because by vetoing the enactment of such policies and giving them the force of law, we prevent huge international problems for every American.
The reason UN has been taking such action is because Obama wanted them to. Trump does not. Trump now controls money to UN.
End of problem.
End of discussion.
And control how we live... like climate change hoaxes and amongst other things. Unless you like one world order.
