Obama's first days of Peace

On February 27, 2009 - the USA Today reported that the nominations for the Nobel Peace Prize had been made.
OSLO (AP) — President Obama and his French counterpart Nicolas Sarkozy are believed to be among a record 205 nominations for the 2009 Nobel Peace Prize.

The secretive five-member awards committee, which released its final nominations count on Friday, keeps the names of candidates secret for 50 years. But some of the thousands of people with nominating rights do announce their nominees.

Question: what did Obama do in one month to deserve the nomination?
