>> I think we're having very good dialogue. We have made progress. There's no question about it.>> President Donald Trump on Tuesday hailing a possible breakthrough in reigning in North Korea's nuclear program, and saying, he is open to talks.>> The statements coming out of South Korea and North Korea have been very positive.
That would be a great thing for the world.>> North Korean Leader, Kim Jong-un was all smiles as he met a delegation from the south for landmark talks. But former US officials familiar with the North are warning against getting swept up in the moment. They say Kim's offer of nuclear talks could well go the way of past initiatives nowhere.
Reuters foreign affairs reporter, Arshad Mohammed.>> All of the former officials that I've talked to have lived through past negotiations with the North, and have seen the two major agreements that have been reached between the United States and North Korea in the past fall apart. And none of them expects really ultimately much different, this time around.
>> I'd like to be optimistic, but I think maybe this has gone further than anyone's taken it before.>> It will be hard to overlook the decades of failed overtures each sparking just as much optimism in their time. In 1994, President Bill Clinton struck the agreed framework with Kim's father, Kim Jong-il, after intensive talks.
But that unravelled, after George W Bush included North Korea in his Access of Evil. Bush himself sponsored six party talks under which North Korea was to give up its nuclear program. But they too fell apart. Then in 2007, another potential deal but that too fizzled.>> This should have been handled long ago.
This should have been handled over many years by many different administrations, not now.>> Veterans of talks with North Korea say, any hope made be dimmed from the start by a statement by the North, that it wouldn't need a nuclear program if military threats against it were removed.
They say, those words are code for a demand, that the US withdraw its troops after six decades on the Korean Peninsula, a demand military officials say the US would never meet.>> One way or the other, we have to do something. We cannot let that situation fester. We cannot let it happen.
