Despite these efforts, the regime lacked a broad popular base or a mass movement supporting it. The Greek people were generally apathetic, without actively opposing Metaxas. Metaxas also improved the country's defenses in preparation for the forthcoming European war, constructing, among other defensive measures, the "Metaxas Line". Despite his aping of Fascism, and the strong economic ties with resurgent Nazi Germany, Metaxas followed a policy of neutrality, given Greece's traditionally strong ties to Britain, reinforced by King George II's personal anglophilia. In April 1939, the Italian threat suddenly loomed closer when Italy annexed Albania, whereupon Britain publicly guaranteed Greece's borders. Thus, when World War II broke out in September 1939, Greece remained neutral.
