Since its foundation in 1971, the World Economic Forum in Davos has been a byword for the growing consensus around an increasingly globalised world. Now, President Donald Trump is on his way to tell those who consider themselves the global elite that they have been wrong on just about everything.
Mr Trump will be the first serving US president to attend Davos since Bill Clinton in 2000. But Mr Trump won't be the only major world leader in attendance. Indian Prime Minister Narendra Modi will also be there for the first time, as well as French President Emmanuel Macron. German Chancellor Angela Merkel will also join the party after reaching preliminary agreement with the Social Democrats on a new coalition government for Germany last week.
Their presence, along with UK Prime Minister Theresa May and Canada's Justin Trudeau among others, sets the stage for a fascinating face-off with Mr Trump.
Davos can be a great opportunity for leaders to showcase themselves. Last year's meeting was dominated by Chinese President Xi Jinping, whose speech focused on opposing protectionism and painting Beijing as the new defender of free trade in the age of Trump. That burnished the Chinese leader's credentials abroad in the run up to the Communist Party Congress, where he cemented power at home.
The number of big-ticket leaders this year, however, will inevitably make that space more contested. Mr Macron and Ms Merkel will likely use it as a platform to defend their record on migration and security and presenting a liberal, centrist European vision.
That puts Mr Macron in a potentially difficult position. Now Ms Merkel is also showing up, the French president may feel little choice but to join with her on a relatively anti-Trump platform. Mr Macron and the US president, however, are scheduled to meet and the French leader might wish to recreate the bonhomie that characterised their first interaction last year.
For India's Mr Modi, the circus will be a frustration -- he was hoping to follow Mr Xi's example and dominate the conference. But the presence of Mr Trump will also give him the opportunity to cement good relations after a positive meeting between the two men in November. In Davos, they have the opportunity to present themselves as leaders of the world's two largest and most powerful democracies, a strong platform to push whatever ideas they wish.
Many of the other attendees, meanwhile, will almost certainly jump at the opportunity to lay into Mr Trump. That was always inevitable, but has become even more likely after his reported description of African and Caribbean countries as "shitholes".
Much will depend on how rigorously the president can be persuaded to stay "on message" -- and whether the other leaders can steer him toward their own agendas. Last year, his first address to Congress was largely free of Trump-style ad-libbing, regarded by many on both sides of the aisle as one of his more coherent outlines of his worldview. A speech to Nato leaders in May last year, in contrast, was rambling and accusatory.
For his audience back home, the US president and those around him face a difficult balancing act. Mr Trump knows his political base would like nothing more than to see him criticise the chief executives, celebrities and more liberal politicians gathered in the Alps. At the same time, the administration has no shortage of things it would like to achieve. The summit offers unparalleled opportunities for backroom dealing and short and surreptitious meetings.
In an interview with The Wall Street Journal, Mr Trump said his aim in going to Davos was to be a "cheerleader for the country". Treasury Secretary Steven Mnuchin said the president would be heavily promoting his "America first" economic doctrine, a protectionist message that he also pushed heavily on his November trip to Asia. The administration will also hope to make some progress on a host of other topics, such as closing the gap between European nations and Washington on handling Iran and ratcheting up pressure on North Korea.
The US president will be accompanied by the largest US delegation in recent Davos history. In addition to Mr Mnuchin, it is scheduled to include Security Adviser HR McMaster, Secretary of State Rex Tillerson, Commerce Secretary Wilbur Ross and Treasury Secretary Mnuchin. That will allow for an unusually wide collection of policymaker speeches in which the Washington can set out its positions -- or add nuance and explanation to Mr Trump's utterances.
Any speech Mr Trump gives will be his highest-profile overseas address yet. He will also, presumably, be keeping up his own very personal Twitter coverage of all that happens, giving a level of insight into his state of mind -- as well as who has really annoyed him.
According to reporting by Politico, the president will most likely use the speech to set off one what some advisors call a dramatic "stink bomb". Expect the president to lambaste other attendees on free-trade deals that he believes have undermined the United States, express his scepticism on climate change and perhaps the activities of the International Monetary Fund and World Bank.
Little of that will go down particularly well. Much, however, will depend on Mr Trump's own reaction to any criticism. Without doubt, he will lose no opportunity to remind all other attendees that he is the president of the US and they are not.
The president is nothing if not a successful showman. And no doubt he will savour the fact that his speech is scheduled to be delivered as one of the meeting's closing acts. The problem for the rest of the attending elite is that even the most adept manoeuvring won't prevent their own agendas being subsumed by his.
Which is, of course, exactly how he likes it.
