When Shinzo Abe, the leader of Japan's main opposition party, talks about his vision for the country's diplomacy and security, East Asia has every reason to prick up its ears.

He was eager to show his hardline credentials when releasing his party's campaign pledges on Wednesday, presenting himself as a tough nut to crack if he takes the helm for a second time. His vision of a stronger Japanese military with new duties deserves the close attention of East Asian countries.
