Based on my experiences, there does seem to be two dimensions to the Argentine/UK relationship - a high level politically driven one and a more practical day to day military one.
Having worked alongside the Argentines, I sense that both militarys hold each other in mutual respect and would like to do more. I also sense that there is a sensible level of working together done when life is at stake - its a shame that we can't do more together as my exposure to the Argentine armed forces has been of good people who bring very good wine to the party :-)
