quate strength of the U.S. armed forces, to our materiel commitments
to England and the Soviet Union, and to the vast naval and military
responsibilities which the British had elsewhere. But there was also
an underestimation of Japanese capabilities both by commanders in
the Far East and by leaders in Washington and London, and what-
ever alarm may have been entertained over Japanese threats toward
the south, there seems to have been little doubt of the ability of the
associated powers to implement the strategy described in ABC-I .
The overwhelming strength of the Japanese army was recognized,
but inasmuch as its southward movement must be by sea, we counted
on neutralizing, if not wholly containing, that strength by Allied
naval and air striking forces. Initial Japanese successes cut at the very
roots of this concept. By 10 December, the enemy had destroyed or
immobilized the heavy units of the U.S. Pacific Fleet, had sunk the
newly arrived British warships Repulse and Prince of Wales, and had
wiped out in large part our air strength in Luzon and Oahu. Manila
and Hong Kong, already under attack, were doomed, and the drive
for Singapore had begun. With their striking power crippled and
their main bases rendered ineffective, the associated powers could
offer little resistance as the enemy pushed on pell-mell for the Neth-
erlands East Indies. The swiftness of that rush was hardly appreciated
in the first few days of the war, but already it was obvious that pre-
war plans must be reviewed.
Meanwhile RAINBOW No. 5, as revised in November, was in-
voked-against Japan on 7 December, against Germany and Italy on
the I I th-but with the proviso that Army task forces would be desig-
nated and dispatched only in accord with subsequent W a r Department
instructions.‘ Within the Air Staff there was an immediate, though
momentary, reaction in favor of deploying all available air strength
for defense of the Western Hemisphere and, if practicable, of Hawaii
and the Philippines.? Within a week, however, AAF planners returned
to a more familiar theme with a new long-term design for offensive
war. This plan, called AWPD/4 ( I 5 December 1941) was hardly
more than a restatement of the salient features of AWPD/I, with
requirements somewhat inflated under the stimulus of war. It called
for an air force of some 3,000,000 men and 90,000 planes, to be
achieved by “giving NATIONAL FIRST PRIORITY TO THE
PRODUCTION OF AIRCRAFT.” * This plan was not accepted.
It was clear that the role of the AAF could be determined only in
