Was there some kind of territorial dispute or something?

Nobody that I talked to in Argentina expressed the slightest annoyance that I was English; nobody brought up the obvious issue. However, it does seem that there was a certain amount of official, and even occasionally unofficial, enthusiasm about something:

Written on the granite walls



Displayed as a grammar exercise in the square outside the Presidential Palace



and in engraved aluminium inside the Palace



and on a poster outside the cathedral in Mendoza



and as the name of a major chain of high-end kitchen fitters
