Prime Minister Benjamin Netanyahu may have made an argument that many Israelis support when he warned Congress Tuesday about a potential nuclear deal with Iran, but critics are asking whether it was worth the widening rift with the White House.

The address was broadcast live on Israeli television and radio, and came at a politically sensitive time — just two weeks before a closely contested election in which Netanyahu is seeking a fourth term as prime minister.

Israeli political commentators called it a polished performance by the U.S.-educated politician, but agreed with President Barack Obama's assessment that Netanyahu offered nothing new in his criticism of U.S.-led talks with Iran.
