Hiroshima does not look like a bombed city. It looks as if a monster steamroller had passed over it and squashed it out of existence.

And just as there was something of every Vietnamese in Ho Chi Minh so there is something of Ho Chi Minh in almost every present-day Vietnamese, so strong is his imprint on the Vietnamese nation.

Ho joined the French socialist party, the first Vietnamese to be a member of a French political party.

When you arrive in Hiroshima you can look around and for 25 and perhaps 30 square miles you can see hardly a building. It gives you an empty feeling in the stomach to see such man-made devastation.

My anger with the US was not at first, that they had used that weapon - although that anger came later.

Of thousands of others, nearer the centre of the explosion, there was no trace. They vanished. The theory in Hiroshima is that the atomic heat was so great that they burned instantly to ashes - except that there were no ashes.

My emotional and intellectual response to Hiroshima was that the question of the social responsibility of a journalist was posed with greater urgency than ever.
