Yugoslavia's situation worsened in October 1940 when Italy invaded Greece from Albania, and the initial failure of the Italians to make headway only increased Yugoslav apprehension that Germany would be forced to attack Greece in order to help Italy. In September and November 1940 respectively, Germany forced Hungary and Romania to accede to the Tripartite Pact. In early November 1940, Nedić, who believed that Germany would win the war, proposed to the government that it abandon its neutral stance and join the Axis as soon as possible in the hope that Germany would protect Yugoslavia against its "greedy neighbors". A few days later Prince Paul, having realised the impossibility of following Nedić's advice, replaced him. Germany's planned invasion of Greece would be simplified if Yugoslavia could be neutralised. Over the next few months, Prince Paul and his ministers laboured under overwhelming German diplomatic pressure, the threat of an attack by the Germans from Bulgarian territory, and the unwillingness of the British to promise practical military support. By late 1940, British policy towards the government of Yugoslavia had shifted from acceptance of Yugoslav neutrality to pressuring the country for support in the war against Germany.
