It started with a momentous journey for Kim Jong Un and Korea.

In a move barely imaginable just four months ago, he made his way to the border to meet the neighbours, before stepping into enemy territory and into history.

If watching the first Northern leader to cross into the South since the end of the Korean War was remarkable, what followed next was astounding.

Unrehearsed, on his own terms, Chairman Kim reciprocated, leading President Moon into the North.

Was this a brutal dictator extending the hand of friendship or proving he's an equal?

As the pair made their way towards the talks, beaming smiles replaced the threats of last year.

More on Kim Jong Un

Before they began, Kim Jong Un pledged that the meeting would start a new history of peace, eight hours later the triumphant leaders emerged with an historic declaration.

A commitment to denuclearisation and an official peace treaty are progress, but they are also promises that have been made and broken by the North before.

For this summit to succeed where previous ones have failed we need to know how this will happen, what Kim is demanding in return, and if he's really ready to open up his regime.

Contrasted with the escalating tensions of 2017, the sudden diplomatic gear change since the start of the year has been dizzying.

At times today even Kim Jong Un struggled to keep up, his bodyguards having to sprint with his car to the symbolic planting of a tree to avoid him being late.

While today's announcement plants the seeds of change, they'll wither and die without the backing of Donald Trump and the US.

The third inter-Korean Summit has been a carefully choreographed charm offensive, a meticulous show of togetherness.

But can the head of a ruthless regime really be sincere about peace?

There's no doubt the optics of the day were flawless, but the coming months will prove if it was simply another empty performance.
