Why naval colleges produce political officers

Did the Imperial Japanese Navy put too many political radicals into naval-college teaching?

Advanced schools attract independent thinkers, who may become political activists or define their allegiance chiefly through the navy itself.

Naval colleges seek capable, independent-minded officers to teach. Those officers can become publicly political or avoid party alignment while advancing the navy's institutional interests. Mitsumasa Yonai is the Japanese example of guarded public politics. Reginald Henderson's precise political loyalties were similarly difficult to identify, prompting the suggestion that his allegiance was chiefly to the Navy.
