President Biden vowed during his quest for the White House to make the Saudi crown prince, Mohammed bin Salman, a “pariah” over the killing and dismemberment of a dissident. He threatened the prince again last fall with “consequences” for defying American wishes on oil policy.

Lindsey Graham, the Republican senator, called Prince Mohammed, the oil-rich kingdom’s de facto ruler, a “wrecking ball” who could “never be a leader on the world stage.” And Jay Monahan, the head of golf’s prestigious PGA Tour, suggested that players who joined a rival Saudi-backed league betrayed the victims of the Sept. 11 terrorist attacks — carried out by hijackers who were mostly Saudi citizens.

Now, their words ring hollow.

Mr. Biden, visiting Saudi Arabia last year, fist bumped Prince Mohammed when they met and regularly dispatches officials to see him — including his secretary of state, Antony J. Blinken, this past week. Senator Graham grinned next to the prince — known by his initials M.B.S. — during a visit to Saudi Arabia in April. Also this week, Mr. Monahan jolted the world of professional golf by announcing a planned partnership between the PGA and the upstart Saudi-backed LIV Golf league, suddenly giving the kingdom tremendous global influence over the sport.

“It just tells you how money talks because this guy sits on top of this oil well and all this money, so he can basically buy his way out of everything,” said Abdullah Alaoudh, the Saudi director for the Freedom Initiative, a rights group in Washington and a vocal opponent of the monarchy.
