Takeo Fukuda
As the head of the Self-Defence Force, Nakasone argued for an increase in defence spending from less than 1% GDP to 3% of GDP. He was also in favour of Japan having tactical nuclear weapons. He was labelled "the weathervane" in 1972 because he switched his support from Takeo Fukuda to Kakuei Tanaka in the leadership election, ensuring Tanaka's victory. In turn, Tanaka would give his powerful support to Nakasone against Fukuda a decade later in the fight for the premiership.
