An anti-Iran alliance forged between the leaders of the United States, Israel and Saudi Arabia is faltering as each have become overwhelmed by their own dilemmas, Israel's leading daily Haaretz reports.

“The three leaders who have led the anti-Iran line in recent years were each absorbed in his own domestic crisis this week,” Haaretz wrote on Thursday.

The Israeli paper pointed to the recently intensified impeachment inquiry surrounding US President Donald Trump and pre-indictment hearings threatening the tenure of Israeli Prime Minister Benjamin Netanyahu during the past week as signs that the two leaders were mired in crisis.
