Reports say Donald Trump’s presidency has had a “major impact on how the world sees the United States”, according to a large new study.

The survey, by the Pew Research Center, interviewed more than 40,000 people in 37 countries this year.

It concluded that the US president and his policies “are broadly unpopular around the globe”.

The survey shows only two of the 37 countries have a better opinion of Mr Trump than they had of his predecessor Barack Obama – Israel and Russia.

But the report indicates many feel their country’s relationship with the US will not change over the coming years.

Mr Trump wasted little time in making his mark on world affairs – making clear he expected NATO countries to pay their fair share and encouraging Gulf countries to isolate Qatar in recent weeks.

His presidency has shaken up old allies to the extent that German Chancellor Angela Merkel said, after she met Mr Trump, that she felt Europe could no longer “completely depend” on its old ally.

In fact, it is among the traditional US allies that the confidence has dropped the most, according to the survey – while 86 percent of Germans had faith in Mr Obama, for example, only 11 percent do so in Mr Trump.

In his five months in office, the US president has, however, reached out to important friends – visiting Israel, Saudi Arabia and other countries early on.

His focus on the relationship with Israel, for one, has paid off – though his preferred status among Israelis is also reflective of Mr Obama’s unpopularity there.

India, whose prime minister Narendra Modi met Mr Trump on Monday, is one of the countries that looks on the US president most favourably – 40 percent of respondents had confidence in him compared with 58 percent for Mr Obama.

In 26 of the 37 countries, more than half of respondents consider Mr Trump dangerous.

Having said that, the opinion changes depending on who is answering – those who say they are left-leaning are far more likely to consider him dangerous. In Peru and Brazil, it is those in the centre politically who are more likely to be worried.

Across the board, Mr Trump is seen as a strong leader – Latin American and African countries in particular really believe this.

The downside for him is that very few countries believe he is qualified to be president.
