US feared Falklands war would be 'close-run thing', documents reveal

The US feared the Thatcher government "had not thought much about diplomatic possibilities" for resolving the Falklands crisis when it dispatched a military taskforce 30 years ago, and predicted the conflict would be a "close-run thing" that could well bring about Margaret Thatcher's fall, according to newly declassified American diplomatic cables.
The documents, published by the National Security Archives, an independent research organisation in Washington, also highlight American worries that a protracted war could draw in the Soviet Union on Argentina's side, with far-reaching geopolitical repercussions in an area of the world the US saw as its backyard.
