Opposition Liberal Party leader Ichiro Ozawa reiterated his opposition Sunday to a bill aimed at allowing the Self-Defense Forces to extend logistic assistance to an expected U.S.-led military operation against terrorists.

Speaking on a Fuji TV program, Ozawa said an overseas dispatch of the SDF under the bill is no different from an exercise of collective defense, "though the government says it will not change its constitutional interpretation that the Constitution prohibits" such an exercise.

"Sending the SDF abroad without principles will endanger the future of the state," he said.
