Israeli opposition leader Yair Lapid has painstakingly assembled a coalition government from an eclectic bloc of rival politicians to oust Prime Minister Benjamin Netanyahu. His next task to repair frayed ties with Democrats in the United States could prove just as difficult.

Netanyahu burned his bridges with many Democrats through his outspoken efforts to torpedo then-President Barack Obama’s signature diplomatic initiative: the 2015 Iran nuclear deal. Lapid blames Netanyahu’s personal alliance with former President Donald Trump for the rise of antisemitic politicians in the U.S. Democratic Party, but his overtures to President Joe Biden’s team could be circumscribed by a broad disagreement over the rehabilitation of that nuclear accord.
