Irish born Samantha Power is the nation’s youngest ever ambassador to the UN, but the sometimes the biggest challenges she faces are the ones between diplomacy and diapers.

Each day spent keeping the peace around the world ends with her determination to keep the peace at home, she revealed this week.

Power, 43, who lives on the 42nd floor of the Waldorf Towers on Park Avenue, told the Today show this week that her daily struggle is to bring her 'A-game' to work and to also be there for her 4-year-old son Declan and one-year-old daughter Rian.

'You never feel like you're ... bringing your A-game to everything at the same time. So something gives,' Power confessed. 'And you know, those who say that nothing gives have mastered cloning, I think ...

'And I can feel, you know, even when we leave in the morning just a level of clinginess and, ‘Are you really coming home? Are you really?’ You know, the other day my son said, 'No more security council resolutions.’

Giving the Today crew the tour of lavish apartment Power, the Pullitzer prize winner and Harvard human rights campaigner, admits she behaves like any other mother coming home from a bruising day of negotiations.

Power came to the United States at the age of nine with her parents from Ireland and along the way has learned to juggle her stressful UN job with her home life with her husband, the famed legal scholar Cass Sunstein.

Sunstein is currently the Robert Walmsley University Professor and Felix Frankfurter Professor of Law at Harvard Law School and is 16 years Power's senior.

Powers told the Today Show this week that her biggest challenge is to give her children as normal an upbringing as possible whilst their school run is provided by an armoured SUV, accompanied by a personal security detail on the streets of Manhattan.

Named as 'one of our country's leading foreign policy thinkers' when named as his choice as U.S. Ambassador to the United Nation's in August, President Obama called her a 'long time champion of human rights and dignity.'

Power won a Pulitzer Prize for her 2002 book 'A Problem From Hell: America and the Age of Genocide.'

As the United States' representative on the 15-member Security Council, Power has been leading the way to secure the removal of all chemical weapons from Syria.

'We wouldn't even be in this discussion about getting rid of Syria's chemical weapons if not for the credible threat of military force,' Power said.

'President Obama has not taken that threat off the table. I think Russia is aware that that threat still exists. Syria's aware that threat still exists.'
