In his biography of Thatcher, "Iron Lady" (2004), John Campbell considers that she made a mistake in stating in her speech that "we are fighting a major internal war against terrorism in Northern Ireland and need more troops in order to win it". British government policy, and the policy adopted by the Conservative Party when they entered government in 1979, was to consider the Northern Ireland situation as a police matter, with the army only deployed (as Operation Banner) to assist the civilian authorities. This would be the last time Thatcher would use such terminology concerning the Troubles but may indicate her personal thoughts on the matter. The Soviet ambassador to the United Kingdom, , lodged an official protest about the tone of the speech.
