Many governments lets say have a change of heart at times mind being on that list for sure. England and France are descent size trading parters to each other and are part of many Europeans agreement's. It wasn't a case of France bowing down to England not at all it was France not supporting Argentina's military for attacking the Falkland Islands in the first place. France not supporting Peru during their short 1995 war most likely 60/40 government pressure and losing future business. France now that I look at things had little couldn't gain really by helping either side in 1995. Both Ecuador and Peru are clients, France wants to keep them both remember France is just being to lose huge markets to the United States. Throwing away even small potential buyers isn't the way to go so not helping was there only choice. Brazil also played a large role in that peace process as well and France was knocking down Brazil's door trying to get them to buy Mirage 2000's and other goodies. It seems France had to take a step back too much government pressure for the trouble it may have cause for supporting either Ecuador or Peru at that time. Money wise not not even saying who was right or wrong in both wars, Ecuador, Peru, and Argentina just wern't worth it to France for the amount trouble it might have be aimed at them for doing so, if that makes sense.
Back to 1982 Brazil if I remember correctly wasn't a big supporter of Argentina's government or their military attack at that time either didn't they allow British bombers to land or something like that. A bomber or tanker had engine problems or was low on fuel something like and made a landing in Brazil. I have to look that up I know I saw something on that I may have my facts mixed up on that a little.
