It used to be 'Veni, vidi, vici' – I came, I saw, I conquered. But today? They came, they smiled, they had their photos taken and they talked.
They (i) will keep talking, (ii) they want to be friends, (iii) North Korea will start to think about being nice, (iv) they will send home any remains from the Korean war and (v) ...that's all there is to see folks.
It isn't much but it's a start and if it actually happens then the world will feel safer.
