Abstract: Among the many reasons why the U.S. should not accede to the U.N.

Having failed to impose their agenda on the U.S., climate change alarmists and other environmental activists are preparing the legal ground and claimants to sue the U.S. if it joins UNCLOS. Even the threat of such suits or failed suits will affect the U.S.
