In early 2015, as the Obama administration was deep into negotiations with Iran over its nuclear program, Republican House Speaker John Boehner invited Israeli Prime Minister Benjamin Netanyahu, who stridently opposed the deal, to address a joint session of Congress. The speech itself, which was intended to convince Congress to scuttle the agreement, turned out to be a dud. Instead of shaming Democrats into opposing the deal, Bibi seemed to unify them in support of it. But the public spectacle of a foreign leader attempting to undermine the American president on U.S. soil at the request of his political adversaries was symbolically striking. Later, polling would show that GOP voters generally felt more warmly about Netanyahu than their actual commander in chief. “Republicans haven’t just rejected Obama. They have adopted Netanyahu as their leader,” Slate’s Will Saletan wrote at the time.
