New York: The crisis in United States-Saudi relations precipitated by the brazen murder of Jamal Khashoggi raises a critical question that the Trump administration plainly wants to avoid: Can the United States continue to cooperate with Crown Prince Mohammed bin Salman?  asked Susan E Rice, the national security adviser during President Barack Obama's second term in an oped piece in the New York Times on Monday.

"The young prince's almost certain culpability in Mr. Khashoggi's killing underscores his extreme recklessness and immorality, while exposing him as a dangerous and unreliable partner for the United States", Rice wrote in what is being dubbed as damning indictment of Saudi Crown Prince so far.

"No astute observer should be surprised to discover that Prince Mohammed is capable of such action. Yes, we may be shocked by how heinous Mr. Khashoggi's murder was, and by how blatant the many lies told by the Saudis have been. Of course, many Americans, from Silicon Valley to the editorial pages of our leading papers, were snowed by the crown prince's promises of reform and the deft marketing of his leadership. But, for those willing to see past his charm offensive, Prince Mohammed had already revealed his true character through numerous impulsive and vicious actions", she wrote.

Rice said, the deadliest exhibit is the warinfo-icon in Yemeninfo-icon, which has cost tens of thousands of lives and killed countless civilians, including children, because the "Saudis arrogantly refuse to employ responsible targeting techniques. It has been a Prince Mohammed operation from the start". 

At home, the crown prince has locked up civil society activists. He imprisoned for months hundreds of members of the royal family and other influential people in the Riyadh Ritz-Carlton and demanded they surrender huge sums of money and valuable assets in exchange for release. He has forced out rivals and close relatives, including former Crown Prince Mohammed bin Nayef. And, as the Khashoggi case suggests, he has undertaken a global purge of Saudi dissidents wherever they reside, she writes.

The crown prince kidnapped the Lebanese prime minister and denied it. He imposed a spiteful, full-blown blockade on neighboring Qatarinfo-icon, another important American partner, and has sought to goad the United States into conflictinfo-icon with Iraninfo-icon. Stung by two mildly critical tweets by the Canadian foreign minister, Prince Mohammed abruptly downgraded diplomatic ties with Ottawa, yanked 7,000 Saudi students out of Canadian universities and limited transport and trade links, she went on.

"As this litany of lunacy shows, Prince Mohammed is not and can no longer be viewed as a reliable or rational partner of the United States and our allies. If we fail to punish him directly and target only those around him, the crown prince will be further emboldened to take extreme actions. If we do punish him, which we must, Prince Mohammed, petulant and proud, is equally likely to behave more irresponsibly to demonstrate his independence and exact retribution against his erstwhile Western partners. Either way, the Trump administration must assume that Prince Mohammed will continue to drive his country and our bilateral relationship over the proverbial cliff".

Unfortunately, according to Susan Rice, King Salman seems unwilling or unable to rein in his 'rogue son'. "With critics cowed into submission and rivals pushed aside, there is no obvious alternative-in-waiting who might provide Saudi Arabiainfo-icon with sober, responsible leadership."

"Absent a change at the top, we should brace ourselves for a future in which Saudi Arabia is less stable and more difficult to govern. In this scenario, the potential risks to American security and economic interests would be grave. The United States was wrong to hitch our wagon to Prince Mohammed, but we would be even more foolish to continue to do so."

Looking ahead, Rice suggested, Washington must act to mitigate the risks to our its interests. "We should not rupture our important relationship with the kingdom, but we must make clear it cannot be businessinfo-icon as usual so long as Prince Mohammed continues to wield unlimited power. It should be United States policy, in conjunction with our allies, to sideline the crown prince in order to increase pressure on the royal family to find a steadier replacement."

Rice urged USinfo-icon should start by leading the push for an impartial international investigation into Mr. Khashoggi's killing. "We must be consistent and public in our judgment that the United States believes the killing could not have occurred without Prince Mohammed's blessing or, more likely, his order."

Next, Rice said  US should terminate all military support for the 'misbegotten Yemen campaign' and pressure the Saudis to reach a negotiated settlement. 

"We should immediately suspend all American arms sales to the kingdom and conduct a careful, comprehensive review of any future deliveries, halting all but those we determine, in close consultation with Congress, advance United States national security interests."

Finally, Rice writes," we should stop following Prince Mohammed down blind alleys and bring a healthy skepticism to our dealings with him, particularly any that require relying on his word or judgment.

We need to stop privileging Jared Kushner's relationship with the crown prince, and finally fill the vacant ambassadorship to the kingdom, to engage with a broader range of senior Saudi officials. President Trumpinfo-icon's inexplicable infatuation with Prince Mohammed must end, and he must recalibrate American policy so that it serves our national interests -- not his personal interests or those of the crown prince."
