In just 50 days, Donald Trump has upended our world. He has ripped up rules, attacked allies and sided with enemies.
A country we thought for decades had our backs is no longer a reliable partner.
We travelled thousands of miles to ask what that means for our lives and millions of others – from the sweltering backstreets of Africa to the frozen wastes of Greenland and Finland’s tense border with Russia.
Donald Trump‘s supporters at home and abroad see him as the disruptor-in-chief who will bring peace and prosperity, putting America first.
But to many others we found he threatens chaos and a far darker future.
While Mr Trump may be challenging convention and bringing fresh thinking, his critics say he is moving too fast and erratically. His first 50 days in office, they claim, have weakened America’s place in the world and that will be exploited by rivals.
Risk of resurgent epidemics in Kenya
We went first to Kenya. The focus in the West may have been on Mr Trump and Russia but in the developing world, it’s the end of US aid that is grabbing the headlines.
On the frontlines of Africa’s war on HIV we heard Mr Trump’s actions being compared to an act of “biological warfare”.
Even among allies and admirers of the American president, there is deep unease and fear about what could come next, most of all the risk of resurgent epidemics of diseases like HIV, TB, malaria, ebola, and polio.
In one of Kenya’s poorest neighbourhoods in Nairobi, we joined health workers on their rounds, down sewage-filled alleyways into cramped, overcrowded buildings.
In a one-room home, we met a young mother who is dependent on American aid. Anne is HIV positive and needs daily medication and nutritional support for both herself and her one-year-old son. She is terrified for their future because of the cut in US aid.
“I’m so worried,” she told us, “because if it carries on like this the medication could run out. When the medicine is not there, the protector of my body is not there, so anything can just pass through me.”
‘We had no warning’
Kenya received $850m (£658m) in aid a year and that has now been abruptly severed. A US Supreme Court decision against the Trump administration may restore some of that but there is complete uncertainty about what happens next.
Martha, a healthcare manager in Nairobi, spelled out what is at stake: “We had no warning. We could not prepare the households. It was so sudden.
“We expect more death. We expect more children to die before the age of five. We expect more death for children living with HIV and it is going to be bad,” Martha said, adding that more than 20,000 children who use her organisation’s services will be affected.
83% of all US aid contracts cut
The Trump administration says the aid has been only been suspended for 90 days pending a review. But in reality, many key programmes appear to have been shut down completely.
After a 45-minute flight west of Nairobi to Kisumu, we saw what is happening away from big cities. The impact seemed just as severe.
At one provincial hospital US Agency for International Development (USAID) signs were everywhere but on doors that are now shut. It had been a hub for patients to receive their treatment but that’s now in doubt.
Staff told us there were just two months of supplies left for some medication, and less than a month for others, because there have been no more deliveries.
Patients were stockpiling drugs, said doctors, panicking for the future.
‘Biological warfare’
The US-supplied ammunition for Africa’s war against HIV, malaria, TB and other diseases is running out. It has taken decades and billions to bring them under control. The fear is of a return to epidemics not seen for years.
