Reporter's Perspective

As the Chuseok holiday passes, the primary flashpoints of the political landscape are shifting toward the clash between the executive and judicial branches, as well as security disputes over the handling of North Korean POWs and the DMZ accident. Depending on the Democratic Party's plan to submit contentious bills to the plenary session next week and the People Power Party's filibuster counter-strategy, confrontation within the National Assembly is expected to materialize. At the same time, this is a phase where diplomatic issues regarding North Korea and the US are becoming reality following the ROK-US-Japan foreign ministers' joint statement. A key point to watch is whether the ruling-opposition political reform showdown will reignite following the People Power Party's declaration to refuse constitutional reform discussions.
