"Claiming that 193 countries signed on is a meaningless statement, which is likely why it's made. The meaningful way to view it is that 193 countries agreed that the U.S. should harm itself and to gladly pay on Tuesday for the U.S. to harm itself today," said Chris Horner, a senior fellow at the Competitive Enterprise Institute and a leading critic of the Paris pact. "There's a stark difference between agreeing to sign on to Paris and agreeing to do something, to undertake pain. In essence, they rented their signature for the promise of Paris-related wealth transfers. But for them to promise to do anything beyond take our money and impose the agenda, too, would really cost us."
