of western Europe as per Canada's NATO commitments as the number three mission. United Nations peace-keeping missions as the number four mission. In May 1969, the Defence Minister, Léo Cadieux, visited the capitals of western Europe to tell the leaders of the western European states that Canada would be drastically cutting its NATO commitments later that year, and henceforward, Canada's role in NATO would be only to provide token contributions to the defence of western Europe. On 23 June 1969, Cadieux announced to the House of Commons drastic cuts in defence spending as Canada's commitments to NATO were going to be reduced. In June 1969 in a speech to the graduating class at Queen's University, Trudeau warned that United States was descending into anarchy with race riots and student protests, and the violence in the United States could "easily spill" into Canada, which he claimed required more soldiers in Canada. In September 1969, it was announced that half of the Canadian Forces stationed in West Germany were to be pulled out with the remainder to be moved to Lahr in southern West Germany to operate under American operational command; previously, the Canadian Forces in West Germany had been stationed in northern West Germany under British operational command. The historical links between the British and Canadian armies ended in 1969. The major operation for the Canadian Forces in 1969 was domestic when the Service de police de la Ville de Montréal went on strike on 7 October 1969, leading to rioting in Montreal that required the Army to put down. In 1970 Cadieux's successor as Defence Minister, Donald Macdonald, announced to the House of Commons that the safeguarding Canada's sovereignty and helping with "the social and economic development of Canada" were the main purpose of the Canadian Forces. In a 1970 white paper, Defence in the Seventies, it was announced the "Priority One" of the Canadian Forces was now internal security, with the future enemy now envisioned as the FLQ instead of the Soviet Union. The Regular Force was downsized in 1970, and the number of regular infantry battalions was reduced from 13 to 10. This was achieved by reducing the Canadian Guards to nil strength, returning both the Queen's Own Rifles of Canada and the Black Watch (Royal Highland Regiment) of Canada to their militia only status and rebadging soldiers into three new battalions of the remaining Regular Regiments.
