As per the security legislation, which lifted the government’s long-standing ban on Japan engaging in acts of collective self-defense, the revised ACSA paves the way for Japan providing logistical support for the U.S. military not only in case of armed attack on Japan but when an attack on Japan’s ally threatens the nation’s own survival even though the nation is not under direct attack. The 1998 revision provided for support for U.S. forces in contingencies in areas surrounding Japan — which effectively assumed a security crisis in and around the Korean Peninsula — but the geographical restriction has been lifted and the SDF will now be able to support the U.S. military in emergencies taking place effectively anywhere around the globe that are deemed to gravely affect Japan’s peace and security. The new blanket law for deployment of the SDF for support for other militaries — such as the refueling in the Indian Ocean for other naval vessels of countries taking part in the fighting in Afghanistan following the 9/11 attacks on the U.S. and deployment of Ground Self-Defense Force troops in Iraq — also expands the scope of SDF missions overseas.
The Abe administration is also seeking to add a new mission to the SDF troops deployed for the U.N. peacekeeping operation in South Sudan
