The British Prime Minister, Mr Tony Blair, met the democratically elected President of Argentina, Mr Fernando de la Rua, from whose generals Ms Margaret Thatcher wrested back the Falkland Islands in 1982, yesterday. And the event was not marred by protests.
Having met in Brazil, the two leaders met again on Argentine soil, menaced by nothing more alarming than photographers.
Mr Blair met the Argentine and Brazilian presidents in just the kind of tropical rainforest the world's environmentalists and protesters are trying to protect from globalisation.
The deforested farms are now only a few miles away. But this being the Iguazu national park, all its trees and animals are protected.
The three leaders were also protected, so much so that when Mr Blair shook hands with Mr de la Rua in the presence of their host, President Fernando Herique Cardoso of Brazil, the event was witnessed by two TV cameras, one still photographer and a Guardian journalist.
The Iguazu marks the border between Brazil and Argentina.
While the Falklands war was not on the agenda for discussion between the leaders of the former rival nations, Mr Blair said: "We have our respective positions. What has happened in the past is in the past." Mr de la Rua also touched on the issue at a news conference saying: "We have said that our claims over the Malvinas [Falklands] islands are absolutely along peaceful paths."
Mr de la Rua had taken time off from a hefty financial crisis. Far from wanting to dwell on the Falklands war, he expressed gratitude for what his visitor had called his "solidarity" with Argentina as it struggles to avoid a devaluation and a debt default.
Over lunch they discussed, among other things, globalisation and the need for rich countries to open up their markets.
It is Mr Blair's new crusade. Now that reform of the public services at home is sort-of-under way, he is looking for new horizons and new allies to evangelise for global free trade.
Yesterday's free trade talk took place on the Brazilian side of the falls. Mr Cardoso then flew home, leaving Mr de la Rua to dash across the bridge and do it all again for Mr Blair and his wife, Cherie, at the Sheraton Hotel on the Argentinian bank.
The media accompanied the Blairs, including the Sun whose notorious "Gotcha" headline after the sinking of the Belgrano immortalised the event. No one mentioned it, however.
