Inside the kingdom, Prince Mohammed is pressing ahead. Last week, Saudi Arabia began offering tourist visas, betting that an influx of foreign visitors would bring in more cash. And it is hosting high-profile entertainment and sporting events aimed at creating jobs and shedding the kingdom’s reputation as hidebound by a hyper-conservative interpretation of Islam.
While the prince has yet to make significant progress in his efforts to regain his standing in Washington, Mr. Satloff did not rule it out in the long term.
“It is still very early,” he said. “What people are looking for is actions. The words are not sufficient.”
Prince Mohammed has vowed that justice would be done, but Saudi officials have refused to cooperate with international investigators, and the trial in Riyadh of 11 suspects in Mr. Khashoggi’s killing has been shrouded in secrecy. Diplomats who have attended trial sessions have been sworn to silence.
One year after the killing, the kingdom still has not revealed the whereabouts of Mr. Khashoggi’s body, which agents cut up after his killing. Ms. Callamard, the United Nations official, said the Saudis have failed to take sufficient steps to address the crime.
“The main moves have been either of a public relations nature, to try to spin the issue, or to ignore the issue altogether,” she said. “I think the expectation has been all along that people will move along and stop focusing on the issue, and that is not happening.”
Speakers at the memorial in Istanbul on Wednesday said that Mr. Khashoggi’s voice against the oppression of dictators was only growing louder with his death.
“If they cannot stop oppressing us, we will not stop resisting,” said Mohamed Soltan, a human rights activist and friend of Mr. Khashoggi’s. “We are smarter, and we are not restricted by the limitations of power, and history is one our side.”
