In a chaotic session rife with yelling and wrestling, the ruling bloc bulldozed two disputed security bills through a special committee in the Upper House on Thursday, taking the penultimate step toward enacting legislation that will subvert Japan*s pacifist approach to world affairs.

The bills, designed to expand the types of overseas missions that can legally be undertaken by the Self-Defense Forces without amending the Constitution, were expected to be enacted by a full session of the House of Councilors later in the evening or early Friday.

When Yoshitada Konoike, chairman of the special committee, tried to put the bills up for a vote at around 4:40 p.m., dozens of lawmakers from the opposition camp mobbed him in an attempt to stop the procedure. Lawmakers from the ruling bloc then rushed to protect him, turning the session into a mob scene.
