question:
U.S. President Donald Trump attempted to reset his relationship with Africa on Monday, as he hosted Nigerian President Muhammadu Buhari.
Buhari is the first sub-Saharan African leader to have a White House summit with Trump, who has been criticized for reportedly making derogatory comments about Africa.
During his public remarks with Buhari, Trump focused mostly on common goals and shared interests, such as fighting terrorism and expanding trade.
"We love helicopters — he loves them more than I do," joked Trump, referring to his administration's decision to approve a $600 million military sales deal to Nigeria.
Buhari thanked Trump for approving the deal, which the administration of former President Barack Obama had suspended over allegations of human rights abuses.
"I worked it out so that now you can buy the helicopters that you want," Trump said, adding, "We make the best military equipment in the world, and our friends can now buy it."
Human rights groups have accused the Nigerian military of torture, rape and extrajudicial killing in its almost decade-long campaign against the Boko Haram extremist group.
Tens of thousands of people have been killed in the insurgency, and hundreds of schoolgirls kidnapped, as the group gained notoriety and spread to neighboring countries, posing one of the most severe threats to West Africa's Sahel region in recent years.
Although Nigeria has been a major partner in the U.S. fight against Islamist extremists in Africa, relations have faced challenges over the past year.
In January, Nigeria joined a list of outraged African countries demanding an explanation from the U.S. ambassador after Trump's reported vulgar comments referring to African countries.
Asked whether those comments came up during his private meeting with Trump, Buhari declined to comment.

"I'm very careful with what the press says about other than myself. I'm not sure about, you know, the validity or whether that allegation was true or not. So, the best thing for me is to keep quiet," Buhari said. Question: Who is the Nigerian president?
answer:
Muhammadu Buhari


question:
SEOUL, SOUTH KOREA — The U.S. election calendar could be a key factor in determining the scope and timing of a potential deal to end the North Korean nuclear program.
Planning is progressing for both the upcoming summit between North Korean leader Kim Jong Un and South Korean President Moon Jae-in at the end of April and the expected meeting between U.S. President Donald Trump and Kim in late May or early June.
President Trump said Tuesday that there had been talks at "extremely high levels" between his administration and the North Korean government. Later it was reported that Mike Pompeo, the director of the Central Intelligence Agency and a secretary of state nominee, met recently with Kim Jong Un in Pyongyang.
Trump also noted the talks have been marked by "a lot of goodwill" and that "there has been a major change in terms of North Korea's behavior," since Kim's Olympic outreach this year, in which he sent a large delegation to the Pyeongchang Winter games in South Korea, suspended nuclear and missile tests, and expressed a willingness to engage in denuclearization talks.
The turn toward diplomacy has reduced, for now, the potential for conflict over the North's accelerated efforts last year to develop an operational nuclear-armed intercontinental ballistic missile that can reach the U.S. mainland.
The North Korean leader's decision to engage in denuclearization talks was likely motivated by both Trump's "maximum pressure" campaign, which increased sanctions and the threat of military action against the North, and by South Korean President Moon's reassuring outreach efforts to improve inter-Korean relations.
Trump's motivation in pursuing a nuclear deal with North Korea, in addition to resolving a growing national security threat, could also have a political component.
According to North Korea analysts at the Sejong Institute in South Korea, the Trump administration is likely calculating how achieving such an agreement could help boost the president's chances for re-election in 2020.
"If I were Trump, I would try to make a tangible accomplishment on the North Korea nuclear issue within the first term by 2020, and in my personal opinion, that would be a really huge achievement for Trump," said Lee Sang-hyun, with the Sejong Institute. Question: Who departed from his normal behavior by sending a delegation to the Olympics?
answer:
Kim Jong Un


question:
The doctors told me I would be placed on a seventy-two hour hold for observation. Knowing this was the only way out, I obeyed and diligently signed all the papers. I hated my parents but still felt the inescapable drive to prove to them that I was worth something. I had to show them I wasn't crazy. As the hours passed, I was shown to a blank room with plastic sheets and plastic pillows, which caused me to wonder what kind of distant confused souls had been imprisoned in this sterile place. There were bars on the windows and the only door out of the unit was locked 24/7. I knew my only refuge for the time being would be through the hour a day art therapy class and the smoke breaks I could take at will. They had given me a legal pad after my parents had told them of my affinity for writing. With it I set to work on the flow of words and the river of thoughts, both dark and hopeful that careened through my tired mind. Instead of sleep, I would write. I expressed my vicious frustration for the place and thought constantly of the passing hours, counting them down as they went. Because of this I was thankful for the eight to ten I would use up easily in my escapes to the world behind my eyelids. There I was free and could experience a life unhindered by limitations of ethics or gravity. When I'd awake I'd write what I could remember of my escapes on the obtrusive legal pad. I had the suspicion that the attendants would come in and read my thoughts as I was eating meals or watching TV and I wondered if this was hindering my ability to get out. I wondered what kind of opinions and judgments they were forming about me. I had bared my soul on those pages explaining desperately how the thoughts would not leave even in this place, where it mattered most that they were gone. The fuckers would never leave. Maybe I was crazy. Question: Who might have been forming judgments about the speaker?
answer:

attendents
