The document discusses the international isolation of the USA during the Vietnam War and how this contributed to their defeat. It notes that while some countries like South Korea, Australia and New Zealand sent troops, overall support was less than hoped for. America received negative media coverage that opponents used for propaganda, reducing further support. A lack of global support forced the US to provide most money and soldiers, which it could not sustain, unlike North Vietnam which received aid from the USSR and China. European allies like France and the UK declined requests to send troops, despite having Asian colonial experience that could have helped.
