about getting its existing radar equipment properly integrated with the local command and control in the year it had been available and operational in Hawaii before the attack. Leisurely radar training continued and the recently organized early warning center was left minimally staffed. Anti-aircraft guns remained in a state of low readiness, with ammunition in secured lockers. Neither Army long-range bombers nor Navy PBYs were used effectively, remaining on a peacetime maintenance and use schedule. Short evidently failed to understand he had the responsibility to defend the fleet. In Short's defense, it should be noted he had training responsibilities to meet, and the best patrol aircraft, B-17s and B-24s, were in demand in the Philippines and Britain, both of which had higher priority (he wanted at least 180 heavy bombers, but already had 35 B-17s, and was getting 12 more). Little was done to prepare for air attack. Inter-service rivalries between Kimmel and Short did not improve the situation. Particularly, most intelligence information was sent to Kimmel, assuming he would relay it to Short, and vice versa; this assumption was honored mostly in the breach. Hawaii did not have a Purple cipher machine (although, by agreement at the highest levels between U.S. and UK cryptographic establishments, four had been delivered to the British by October 1941), so Hawaii remained dependent on Washington for intelligence from that (militarily limited) source. However, since Short had no liaison with Kimmel's intelligence staff, he was usually left out of the loop. Henry Clausen reported the war warnings could not be more precise because Washington could not risk Japan guessing the U.S. was reading important parts of their traffic (most importantly Purple), as well as because neither was cleared to receive Purple. Clausen does not answer why Washington could not have said "an exceptionally reliable source" was involved, with very strong instructions to pay attention. Additionally, Clausen claims military men of Kimmel and Short's seniority and background should have understood the significance of the warnings, and should have been more vigilant than they were, as for instance in scouting plane flights from Hawaii, which were partial at best in the period just before the attack. All other Pacific commands took appropriate measures for their situations. Like most commentators, Clausen ignores what the "war warnings" (and their context) explicitly warn, though indistinctly, against. Washington, with more complete intelligence than any field command, expected an attack anywhere
