The rest of South America view Argentina as arrogant and bullying , and apart from Peru , did nothing to help them .In retrospect I feel that most of the immediate South American countries did something to aid the UK in 1982 even if their true allegiances lay with our other enemies.
Brazil allowed the Vulcan to land (ok, we got it back eventually) and Uruguay landed the Argentine prisoners - two countries that I would never have expected to assist at the time - and Chile helped in a number of ways, certainly over and above the what the Thatcher / Pinochet relationship spawned. The other Latin American countries either were too far away or didn't have anything to give, such as Paraguay.
Yes, the Dutch supported in the best way they could although that could apply equally to other friendly European countries, not forgetting that the Iron Curtain was still in place.
As for France, they gave us considerable aid having supplied Argentina (and us) with weapons beforehand but, for me, our biggest Allie at the time was the US for many reasons, most of which have been aired on this thread already. Even though Haig was backwards and forwards and Reagan was continuing his special relationship with Thatcher, she wasn't having any of it.
My point is that we never really thought that the Argentine junta would even attempt to invade the Falkland Islands. When they did it took a massive amount of everything by the UK - from planning, sheer professionalism, resources, bravery, loyalty and courage for us to regain what was ours. I never was a big fan of Maggie generally and I can take or leave the US and its citizens but, without their efforts and the efforts of other nations, our success would have never happened.
I also believe that we did the Argentinian people a service by our actions which prompted the fall of their vicious Junta. The fact that they have trodden a very thin line since then is neither here nor there. Just my thoughts on a lovely evening, nothing more...
Chile had been the target of Argentine aggression for years over the Beagle Channel and ownership of some of the islands in it . There had been shoot outs on the islands , some claim up to battalion strength , but I'm not sure about that
In 1978 , they very nearly went to war . There were bombers in the air and blackouts in both countries , a last minute intervention by the Pope prevented that one kicking off , so Chile were happy to be on our side .
Uruguay has no truck with Argentina . It was part of Argentina 'till 1833 when Britain and France supported it's independence in order to create a buffer state between Argentina and Brazil ( the only real regional superpower ) and Argentina have been sneering and contemptuous of them ever since , and vice versa .
Argentina stole over half of Paraguay's land mass in a war in the 1870's and that still rankles , so they weren't going to help.
Peru have had a border dispute with Chile for well over a century and hoped to gain something from an alliance with Argentina .They actually sent Mirage III's and pilots to Argentina , but the planes chosen were obviously the ropiest and only useful as a source of spares .
Brazil has a far more outward and pro western outlook than the rest of the continent and would never in a million years have got involved in helping Argentina .
