Nixon was right when he said the Vietnam was our (U.S.A) Boer War

Richard Nixon was right when spoke ( I think it was at Oxford) saying Vietnam was our (U.S.A) Boer War.
Some say the Boer War was the beginning of end of rule Britannic. For the Boer War and Vietnam was P.R nightmare,indeed, a the dream glory of nation had cold water to break it up.
The British public thought the War with Boers with be easy but it was anything but and even when look victory for British the Boers went into hills and fight a guerrilla war. In respond British chief of staff Lord Kitchener take a scorch-earth policy that burn farm, put families suspected of collaboration with the Boars in internment camps,including women and children. Inadequate food and sanitation lead to death of many.The British public never quite got over the Boer War and the British the war, but it was pyrrhic victory.
Vietnam proved like with British in the Boar War there are limits to a great power in war and public opinion can turn very quickly against the war, leaving future policy makers with limited options.
