WASHINGTON: With the return to the White House of Donald Trump, the United States and the world are set for a major new shakeup as the nationalist president turns the page on four years of nurturing allies and confrontingfoes.

Trump`s victory over Vice President Kamala Harris will likely have the most immediate reverberations in Ukraine, where the Republican has mused aboutquickly ending the war by forcing concessions by Kyiv to the Russian invaders.

Trump is expected also to offer robust support to Israel, as he did during his first term from 2017 to 2021, and unleash major new pressure on Iran`s clerical state.

After Trump`s first term, outgoing President Joe Biden put a priority on restoring historic US relationships, which again could see tumult as Trump accuses allies of freeloading off the US military and renews questions about Nato, a bedrock of US foreign policy since the Cold War.

On the campaign trail, Trump has raged against China, with both he and Vice President-elect J. D. Vance casting theAsian power as an enemy. Trump, however, has also insisted that he has a strong relationship with Chinese President Xi Jinping a sort of emphasis on personal diplomacy not entirely different than Biden.

Trump`s personal style could see more fireworks in Latin America, where key US partners Brazil and Colombia and now Mexico are led by leftists.

One of Trump`s key campaign promises the mass deportation of millions of undocumented immigrants could threaten havoc in the region if carried out, although Trump managed a stable, transactional relationship with Mexico`s leader in his first term.

Trump is not known to have an interest in Africa and is unlikely to push for renewalnext year of the African Growth and Opportunity Act, a key trade pact and priority for the continent, although Republican lawmakers support reauthorisation.

Unrestrained `Trump 2.0` Trump has broken sharply with the postWorld War II consensus of the two major parties on building military and diplomatic alliances around the world, pursuing an `America First` platform of promoting US primacy above all, especially on trade.

Brian Finucane, a former State Department officialnow at the International Crisis Group, said Trump could be emboldened compared with his last term.

`A Trump 2.0 would be very different. He would not have any of those figures who didin fact restrain Trump at some point and in some fashion including at the Pentagon, Finucane said.

Trump has already raised fears in Taiwan by publicly questioning whether to defend the self-governing democracy, which Beijing claims and has not ruled out seizing by force. Biden, by contrast, went further than previous US presidents by explicitly saying he would send US troops to defend Taiwan.

In the Middle East, Trump has reportedly told Prime Minister Benjamin Netanyahu to enjoy free rein in the war in Gaza for the two months until Trump takes office. In his first term, Trump fulfilled a wish-list for Israel including moving the US embassy from Tel Aviv to Jerusalem.-AFP
