Some context for this? In 1960, Japanese Prime Minister Kishi "had opposing Diet members forcibly removed from the legislative chamber and rammed through a favorable vote"

I'm not sure what specific context you're looking for. Japan in the 1950s was incredily polarized between right and left wing movements. The latter vehemently opposed to the renewal of security treaty because of the dangers of dragging Japan into America's overseas wars in violation of the peace constitution.
