SCRIPT:
It was Donald Trump's foreign agenda that left much of Washington's political establishment most alarmed during the election.
But as the 45th President of the United States has settled into The White House, his foreign policy has begun to look more typically American.
Donald Trump called Nato obsolete before his inauguration. But after meeting with the Nato Secretary General on Wednesday, the president said the alliance had listened to his criticism and changed.

The President reiterated his call for Nato members to meet their commitment to pay 2 per cent of their GDP into the alliance.
Secreatry general Jens Stoltenberg agreed each nation must contrubute their fair share.
Nato allies will be reasurred by Donald Trump's new support. And it wasn't the only policy reversal by the President on Wednesday.
In an interview with the Wall Street Journal, the president announced he no longer considers China a currency manipulator. This as the US seeks more support from Beijing to contain North Korea's nuclear threat.
And thousands of miles away in Russia, the honeymoon between Donald Trump and Vladimir Putin appeared to be over.
The US Secretary of State Rex Tillerson was met with a frosty reception as he sought to pursuade Moscow to back away from its support for Syrian president Bashar al-Assad.
After meeting with the Russian Foreign Secretary Sergei Lavrov, Rex Tillerson made it clear how sour relations had become.

Both ministers said they'd agreed to work towards a stable and unified Syria and defeating the so-called Islamic State.
Mr Lavrov said there was no evidence the Syrian regime was behind last week's chemical attack. Mr Tillerson couldn't disagree more.

Rex Tillerson also spoke with Vladimir Putin in the Kremlin - the very fact that meeting took place suggests Russia is still open to improving relations with Trump's administration.
Back in Washington, the US President said he was determined to make the world a better place.
CLIP
This is an administration still finding its feet on the international stage - and perhaps Donald Trump is learning that a radically different approach to foreign policy is tougher to implement than he thought.
