Japanese Lawmakers Tuesday Look A Historic Step Away From The Country's Pacifist Constitution And Approved The Right To Collective Self-Defense Or The Ability To Come To The Aid Of A Friendly Country. A Move That Pleases Washington And Angers Beijing. China, Which Is Involved In A Territorial Dispute With Japan, Says Tokyo Is Challenging The Post-War Order And Raising Regional Tensions. The Move Is Also Opposed By Some In South Korea, Which, Along With China, Was A Major Victim Of Japanese Colonial Aggression. Japan Has Been Operating Under A US / Drafted Postwar Constitution That Includes Article 9, Which Renounces War And The Threat, And Use, Of Force To Settle Disputes, And States That Land, Sea And Air Forces, Along With War Potential, Will Never Be Maintained. Jeffrey Hornung, Associate Professor At The Hawaii-Based Asia-Pacific Center For Security Studies, Told VOA's Victor Beattie The Specifics Of the Revised Security Policy Have Yet To Be Spelled Out In Legislation And Expects Some Limitations. He Says The United States Welcomes The Announcement Having Long Advocated A More Pro-Active Japanese Security Presence. Hornung Does Not Believe This Move Guts Article 9.
