To understand Saudi Arabiaā€™s abrupt decision to revolt against Canada over a tweet, experts say itā€™s important to understand the kingdomā€™s aggressive ā€“ and often perplexing ā€“ future leader.

At 32 years old, Crown Prince Mohammed bin Salman has been described as a powerful force of change looking to introduce modern ideas to Saudi Arabia.

The prince earned international notice in June when Saudi Arabia lifted its ban on women driving cars. He also scrapped a 35-year ban on cinemas, met Queen Elizabeth II at Buckingham Palace and once described his vision for the kingdomā€™s future as ā€œthe next Europe.ā€

The princeā€™s youthful approach has won over a large contingent of young Saudi supporters, particularly online, where he is colloquially known as MBS.

Heā€™s the youngest defence minister in the world and serves as the kingdomā€™s deputy prime minister. One day, heā€™ll take over the throne from his father, King Salman.

But bin Salmanā€™s reputation as a forward-thinker is hardly spotless.

Hours after the driving ban was lifted, womenā€™s rights activists who supported the change were arrested. Bin Salman has also led the charge for the war in Yemen, where Saudi-led coalition air attacks have been responsible for nearly two-thirds of civilian deaths, according to the United Nations High Commissioner for Human Rights.

The arrests prompted immediate confusion. Why arrest activists who support your policy? Steven Cook, who has authored several books about Middle Eastern politics, says the move was meant to send a clear message.

ā€œTo warn those within Saudi Arabia that the only reform is the reform that is defined by the crown prince. Itā€™s to say there can be no dissent,ā€ Cook told Ā鶹“«Ć½.

The nationā€™s latest retaliation stems from sent last Friday, that called for the immediate release of imprisoned womenā€™s rights activists.

Saudi Arabia lashed back by expelling Canadaā€™s ambassador, pulling its own ambassador, suspending trade, ordering thousands of students and medical trainees to return to the Middle Eastern nation and suspending Saudi state flights to Toronto.

Some see picking a fight with Canada as bin Salmanā€™s way of sending a message to other countries thinking of questioning Saudi Arabiaā€™s domestic affairs.

If thatā€™s the case, Cook says itā€™s an odd tactic.

ā€œTo try to intimidate a country like Canada, quite frankly, seems like a bizarre way of going about it,ā€ he said.

The real reason behind the move, Cook suggests, is fear. In Cook suggested that Saudi leadership understands that there is a gap between ā€œthe stories the government is telling its citizens about how good life is under its benevolent leaders and how people are actually experiencing it.ā€

If Saudi leadership wasnā€™t intimidated by womenā€™s rights protesters -- and, by extension, Canadaā€™s support for their freedom -- there would be little reason to revolt, Cook says.

ā€œThe Saudis are essentially whipping up national sentiment against Canada because the royal court feels weak,ā€ he said.

Former Liberal foreign affairs minister Lloyd Axworthy says that, ever since the Second World War, Canada has been a leader when it comes to upholding the international rules-based order. Speaking out against human rights abuses, he says, is ā€œnot a new role for Canada.ā€

ā€œI think what is different is that the over-the-top, berserk reactions of the Saudis,ā€ Axworthy told Ā鶹“«Ć½ Channel on Wednesday.

When it comes to bin Salmanā€™s aggressive tactics, Axworthy questioned whether the young leader is ā€œkind of losing it.ā€ He equated bin Salmanā€™s approach to a public relations campaign that does little to modernize his country.

ā€œI think the crown prince has come in with a great fanfare about being a new reformer, a new age, new generation Saudi leader, but he and his father have actually been engaged in some of the worst kind of abuses, including executions, including imprisonment of anybody who has any dissenting point of view,ā€ he said.

Some observers have suggested that Saudi Arabia may be following U.S. President Donald Trumpā€™s example and bashing Prime Minister Justin Trudeau because he embodies the opposite end of the political spectrum. Trump called Trudeau ā€œweakā€ after the prime minster said Canada wonā€™t be pushed around by the U.S. on trade following a tumultuous G7 summit in Quebec.

For what itā€™s worth, Cook isnā€™t convinced that Trump has anything to do with the kingdomā€™s abrasive reaction.

ā€œThe Saudis would be doing this regardless of whoā€™s in the White House,ā€ he said.

Saudi Arabiaā€™s poor record on human rights is regularly scrutinized. Homosexuality is still punishable by death in the kingdom, and Saudi Arabia consistently ranks among the worldā€™s least free nations, Amnesty International has pointed out that activists whoā€™ve spoken out against the kingdom have been silenced with the death penalty.
