Congratulatory messages for Joe Biden poured in from world leaders, spanning from the UK’s Boris Johnson to Emmerson Mnangagwa in Zimbabwe and Brussels chief Ursula von der Leyen.
French president Emmanuel Macron, who initially went to great lengths to court Donald Trump personally despite their opposing views, underlined many western diplomats’ hopes that the incoming Democratic administration would be much more open to working with European counterparts.
“We have a lot to do to overcome today’s challenges,” he tweeted. “Let’s work together!”
Ireland’s premier Micheál Martin was even more forthcoming, noting the president-elect’s strong Irish heritage and saying he is a “stalwart friend” of the country.
Mr Biden’s opposition to Brexit stands in contrast to Mr Trump’s support, raising hopes in Dublin that the new president will use influence to protect the open border between the Irish republic and Northern Ireland.
He invited the president-elect, who has cousins in the counties of Mayo and Louth on the Emerald Island, to visit when possible.
Jens Stoltenberg, secretary-general of Nato, which endured a rocky few years under Mr Trump who called for traditional US allies in Europe to increase their defense spending, said that he hoped to “further strengthen the bond between North America and Europe” under Biden’s presidency. German leader Angela Merkel echoed the sentiment.
Boris Johnson, the UK prime minister, and António Costa, Portugal’s socialist prime minister, put an emphasis on cooperation on climate change with Mr Biden, after the US pulled out of the Paris climate agreement under Mr Trump.
Volodymyr Zelensky, the Ukrainian president whose July 2019 phone call with Donald Trump triggered the outgoing US president’s impeachment trial, warmly greeted Mr Biden’s victory.
From India, Narendra Modi said he hoped Mr Biden would build on his work as vice-president under Barack Obama to “take India-US relations to greater heights”, as he called the entry of Kamala Harris into the White House as a “matter of immense pride” for Indian-Americans.
Not all those hitting Twitter were just out to congratulate Mr Biden. Reinhard Bütikofer, a Green member of the European parliament, taunted Mr Trump by replying to a tweet the president posted earlier on Saturday baselessly claiming that he had won the election by “a lot”.
“Lame tweet, you loser!” said Mr Bütikofer, a member of the European parliament’s foreign affairs committee and its delegations for relations with the US and China. “The high time of alternative facts is over.”
