The Japanese leadership was aware that a total military victory in a traditional sense against the USA was impossible; the alternative would be negotiating for peace after their initial victories, which would recognize Japanese hegemony in Asia. In fact, the Imperial GHQ noted, should acceptable negotiations be reached with the Americans, the attacks were to be canceled—even if the order to attack had already been given. The Japanese leadership looked to base the conduct of the war against America on the historical experiences of the successful wars against China (1894–95) and Russia (1904–05), in both of which a strong continental power was defeated by reaching limited military objectives, not by total conquest.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did the Japanese military leadership think the chances were of complete military victory ove the United States?
Ah, so.. impossible

With nitrides containing aluminium, most often AlGaN and AlGaInN, even shorter wavelengths are achievable. Ultraviolet LEDs in a range of wavelengths are becoming available on the market. Near-UV emitters at wavelengths around 375–395 nm are already cheap and often encountered, for example, as black light lamp replacements for inspection of anti-counterfeiting UV watermarks in some documents and paper currencies. Shorter-wavelength diodes, while substantially more expensive, are commercially available for wavelengths down to 240 nm. As the photosensitivity of microorganisms approximately matches the absorption spectrum of DNA, with a peak at about 260 nm, UV LED emitting at 250–270 nm are to be expected in prospective disinfection and sterilization devices. Recent research has shown that commercially available UVA LEDs (365 nm) are already effective disinfection and sterilization devices. UV-C wavelengths were obtained in laboratories using aluminium nitride (210 nm), boron nitride (215 nm) and diamond (235 nm).
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Shorter wavelength diodes provide wavelengths as low as what?
Ah, so.. 240 nm

Uprisings and demands by African leaders led the UN to assume direct responsibility over the territory. It recognised the South West Africa People's Organisation (SWAPO) as the official representative of the Namibian people in 1973. Namibia, however, remained under South African administration during this time as South-West Africa. Following internal violence, South Africa installed an interim administration in Namibia in 1985. Namibia obtained full independence from South Africa in 1990, with the exception of Walvis Bay and the Penguin Islands, which remained under South African control until 1994.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): In what year was the South West Africa People's Organization formed?
Ah, so..
unanswerable
