Incumbent US President Barack Obama has held a press conference at the white house before heading for Europe on his last foreign trip as president.
Obama plans to reassure his NATO allies of the strength of their partnership. He will travel to Greece for the first time and will meet with Chancellor Angela Merkel in Germany pleading for “a strong integrated and united Europe.”
“It’s essential to our national security and it’s essential to global stability,” he added.
After his visit to Europe Obama will travel to South America to visit Peru.
