TOKYO, Oct. 24 (Kyodo) - Prime Minister Junichiro Koizumi suggested Wednesday that bombing errors are to some extent inevitable, in reference to civilian casualties from the U.S.-led air raids in Afghanistan. At a joint session of the House of Councillor's committees, such as the Foreign Affairs and Defense Committee, Koizumi said the United States and Britain have been "carrying out their attacks aiming at military facilities, but we cannot say the attacks will be 100% on target." "If they could hit only terrorists throughout the attacks, that would be good. But the attacks do not necessarily hit their targets 100%," he said. Koizumi also stated he believes the fight against terrorism will take time, saying, "We don't know how many terrorists are scattered around the world. I'm preparing myself for a long fight." On a bill to enable Japan to send the Self-Defense Forces (SDF) overseas to provide the U.S. with logistical support in military attacks on Afghanistan, Koizumi said he will decide what to do if the fight against terrorism does not end within two years -- the duration for which the new law will be valid. Referring to activities of the SDF, the premier indicated that Japan will be able to provide the U.S. with logistical support regardless of combat zones designated by the U.S. "The U.S. combat zones and the Japanese ones will be different. If Japan concludes that consistent combat is unlikely to take place, we will be able to cooperate (with the U.S.) to transport supplies," Koizumi said. On the issue of limiting the SDF's authority to only U.S. forces facilities and SDF facilities in Japan in another bill to amend the current SDF Law, Koizumi hinted that targets for SDF protection from terrorism may be extended to important non-military facilities such as nuclear power plants in the future. Koizumi said, "If the view emerges that it's better to establish a more secure system in which the SDF and police can cooperate, we must consider it." As a result of a turf war between the SDF and the National Police Agency over their authority, the government dropped its initial idea of allowing the SDF to protect key non-military facilities, including nuclear power plants and the premier's official residence, which are protected only by police.
