UNITED NATIONS (AP) — The United States is ‘urging’ countries that have ratified a U.N. treaty to ban nuclear weapons to withdraw their support as the pact nears the 50 ratifications needed to trigger its entry into force, which 122 countries hope could happen this week.

The U.S. letter to signatories, obtained by The Associated Press, says the five original nuclear powers — the U.S., Russia, China, Britain and France — and America’s NATO allies “stand unified in our opposition to the potential repercussions” of the treaty.
It says the treaty “turns back the clock on verification and disarmament and is dangerous” to the half-century-old Nuclear Nonproliferation Treaty, considered the cornerstone of global nonproliferation efforts.

Fihn dismissed the nuclear powers’ claim that the treaty interferes with the Nuclear Nonproliferation Treaty as “straightforward lies, to be frank.”
“Although we recognize your sovereign right to ratify or accede to the Treaty on the Prohibition of Nuclear Weapons (TPNW), we believe that you have made a strategic error and should withdraw your instrument of ratification or accession,” the letter says.
Fihn said there are about 10 countries that are trying very hard to ratify to get to 50, “and we know that there are a few governments that are working towards Friday as the date. … We’re not 100 percent it will happen, but hopefully it will.”
