TOKYO - Japanese Prime Minister Shinzo Abe said Thursday that his country needs to bolster its security posture amid threats from North Korea and should consider acquiring preemptive strike capability after having to scrap the planned deployment of two new land-based missile defence systems.

Abe said he wants to redefine the meaning of deterrence in the face of the threat from North Korea and its advancement in missile technology.

“We should renew our discussion of adequate deterrence we need, considering North Korea’s missile technology that has advanced since the time we introduced our missile defence systems,” he said.

Abe said that should include the capability to conduct preemptive strikes within the limitations set by the country's pacifist constitution.

"The question is if we should stay within the boundary when enemy capability is dramatically advancing,” Abe said.

Abe has long pushed to amend Article 9 of Japan's post-World War II U.S.-drafted constitution, which renounced war and the use of force as a means of settling international disputes and has been interpreted as limiting the country's armed forces to acting only in self-defence. Abe in 2015 reinterpreted Article 9 to allow self-defence to also include right to fight back for its ally, the U.S. in case of enemy attack.

Abe's comments come just days after Japan's Defence Ministry announced that it would “stop the deployment process” of two land-based Aegis Ashore missile defence systems after it was found that the safety of one of the planned host communities could not be ensured without a hardware redesign that would be too time consuming and costly.

Defence officials had said the two Aegis Ashore units could cover Japan entirely. The country’s current missile defences consist of Aegis-equipped destroyers at sea and Patriot missiles on land.

After being on the back burner in the ruling party for decades, the possibility of gaining preemptive strike capabilities and deploying cruise missiles were proposed to Abe's government by his party’s missile defence panel in 2017.

Abe had since largely avoided the highly divisive topic after seeing his support ratings plunge amid a series of political scandals.

Abe said Thursday that it's time to discuss it again as tensions escalate on the Korean Peninsula.
