You say the US knew and where when the attack was due, all they needed to do
was prep the a/c the night before and launch 30 mins before the attack, plus
wake the sailors up early and have them man the AA guns.

First of all FDR or US did not want to deter japanase or save US ships in
Harbor,what FDR wanted was a spectacular event to schock and awe the Nation.
The first warning of Pearl Harbor attack did not came before hours,days or
weeks before the attack,it came almost one year before attack.
1)On January 27,1941 US Ambassador to Japan ,Joseph Grew sent following message
to Washington:
"Peruvian minister has informed one my staff that he has heard from many
sources,including a Japanase source,that in the event of trouble breaking out
between US and Japan,the Japanase intended to make a surprise attack aganist
Pearl Harbor with all their strength"

Again the date of above message is Jan,27,1941.

2)Later Congressman M.Dies wrote the following:
"Early in 1941 the Dies committee came into possesion of a strategic map which
gave clear proof of intentions of the japanese to make an assault on Pearl
Harbor.The strategic map was prepared by the Japanase Imperial Intelligence
dept.
As soon as I received rhe document I telephoned Secretary of State Cordell Hull
and told him what I had.Secretary Hull directed me not to let anyone know about
map and stated that he would call me as soon as he talked to President
Roosevelt.In about an hour he telephoned to say that he had talked to Roosevelt
and they agreed that it would be very serious if any information concerning
this map reached the news services.I told him it was a grave responsibility to
withold such vital information from the public.TheSecretary assured me the he
and Roosevelt considered essential to national defense"

3)Dusko Popov was a British double agent.
In the summer of 1941 Nazis ordered him to Hawai to make a detailed study of PH
naval base and its nearby airfields.
He deduced that his mission betokened a surprise attack by japanase.In Aug.1941
he reported this to FBI in New York.
Later Hoover bitterly recalled that he had provided Popovs warning abour Pearl
Harbor to FDR but that Roosevelt told him not to pass the information any
further and to just leave in in his ,Presidents,hands"

4)Kilso Haan received definite information from Korean underground that the
Japanese were planning to attack Hawai "before Christmas".Haan contacted Iowa
Senator Gillette and convinced him that information had merit.
Sen.Gillette briefed FDR , but FDR said only"it would be looked into"
5)The Dutch Army in Java on Dec.4 decoded a dispatch from Tokyo to Japan
Embassy in Bangkok, forecasting attack on four locations including Hawai.The
Dutch passed information to US Brig.Gen Thorpe.Thorpe sent total 4 urgent
warning messages to Washington,to last one directly to the desk of Marshalls
intel chief.Washington in return ordered Thorpe not send warning messages
anymore.
Col.Weiijerman,Dutch military attache in Washington,also delivered warning
message to Marshalls staff in person.
6)On Nov,29 Cordell Hull met with the journalist J.Leib and handed him some
japanese intercepts about Pearl Harbor and told him that Japanase were planning
the base and that FDR planned to let it happen.
Leib promised to keep Hulls name out of story and contacted UP Washington chief
Wilson and told him the details without giving the name of his source.
Wilson found story ludicrious and refused to run it but Leib managed to get and
urgent version onto UPs foreign service.


Reality is not your friend, is it?

Is reality your friend?

You haven't addressed why they couldn't defeat the attack yet, also you
havent explained how getting into a different war with Japan helps the USA
get into a war against Germany (or was Hitler in on the big plan too?).


Washington was not interested in defeating attack,much less preventing it.

By sending a war warning?

War warning ?,you make me laugh,unfortunately Kimmel was not under Dutch
command.

Again you feel the need to invent what people are saying.

You really should seek medical help.

I think the people who made Maine Incident (unfortunately too late),Pearl
Harbor (again unfortunately too late) and 9/11 should seek,no not medical
help,but legal help.
