On 22 August, one day after the talks broke down with France and Britain, Moscow revealed that Ribbentrop would visit Stalin the next day. This happened while the Soviets were still negotiating with the British and French missions in Moscow. With the Western nations unwilling to accede to Soviet demands, Stalin instead entered a secret Nazi–Soviet pact. On 24 August a 10-year non-aggression pact was signed with provisions that included: consultation, arbitration if either party disagreed, neutrality if either went to war against a third power, no membership of a group "which is directly or indirectly aimed at the other".

The new interiors sought to recreate an authentically Roman and genuinely interior vocabulary. Techniques employed in the style included flatter, lighter motifs, sculpted in low frieze-like relief or painted in monotones en camaïeu ("like cameos"), isolated medallions or vases or busts or bucrania or other motifs, suspended on swags of laurel or ribbon, with slender arabesques against backgrounds, perhaps, of "Pompeiian red" or pale tints, or stone colours. The style in France was initially a Parisian style, the Goût grec ("Greek style"), not a court style; when Louis XVI acceded to the throne in 1774, Marie Antoinette, his fashion-loving Queen, brought the "Louis XVI" style to court.

In 1951, during the early stages of the Cold War, Menzies spoke of the possibility of a looming third world war. The Menzies Government entered Australia's first formal military alliance outside of the British Commonwealth with the signing of the ANZUS Treaty between Australia, New Zealand and the United States in San Francisco in 1951. External Affairs Minister Percy Spender had put forward the proposal to work along similar lines to the NATO Alliance. The Treaty declared that any attack on one of the three parties in the Pacific area would be viewed as a threat to each, and that the common danger would be met in accordance with each nation's constitutional processes. In 1954 the Menzies Government signed the South East Asia Collective Defence Treaty (SEATO) as a South East Asian counterpart to NATO. That same year, Soviet diplomat Vladimir Petrov and his wife defected from the Soviet embassy in Canberra, revealing evidence of Russian spying activities; Menzies called a Royal Commission to investigate.
