I googled Britannica and got this

And?

And?

Can you find it in Britannica? BTW "and" is not really a question.

Anybody can edit wiki at anytime. That makes it useless as a source for anything other than entertainment related content.

And even some of that is suspect.

I had to supply them with data before my article got approved. And my part was subject to editing by others. I happened to be part of what I was talking about.

Whether or not FDR purposefully provoked Japan doesn’t absolve Japan in the slightest.

They still attacked another country without declaring war. They still did so solely to expand their little Pacific empire they were trying to build. It was in no way self defense

Wrong, an executive order (EO 8381) in 1940 established a three level classification system. Confidential, Secret and Top Secret were the three levels.

Wrong. Top Secret was not on the EO

I don't think you mean that. FDR was eager to be in the war. He followed the McCullom plan pretty damned close. Anyway, it matters not since he put ships and crew into a dangerous position and Japan was pleased, he had done that.

Yeah, but now, anybody else who is authorized can edit your piece at will. Look at pretty much any controversial subject and they are constantly being edited.

I know several people who used to post articles there, but no longer, precisely because their work was constantly being screwed with.

Well, I just checked and all my words are still there.

the Philippines

The Philippines didn't have a naval base that could host US warships, although it was a US colony at the time. Pearl Harbor was the closest one. For Japan to have a free hand in conquering southeastern Asia, hitting the Hawaii base made a strategic sense.

So who was his memo directed about? Was it Italy?

Are you being deliberately obtuse or are you really that stupid? The memo is about Japan, but it doesn't mention any chance of an attack at Pearl Harbor. That was because an attack there was considered impossible for many reasons, two of which are that it was too far for the IJN to operate a carrier task force because Japan lacked the at-sea refueling capability and because Pearl Harbor was considered too shallow for torpedoes to be used. The Japanese torpedoes had to be modified to operate in shallow water here is an excerpt from an article about that:
"

• The Japanese had to modify their Type 91 Modification 2 aerial torpedoes for the Pearl Harbor attack.
• They needed to limit the initial plunge so that the torpedoes would not strike the bottom mud.
• The big stabilizing fins at the rear of the tail cone were an older modification unrelated to this problem.
• The enabling innovation was small wooden fins near the front of the tail cone
• These were gyroscopically driven ailerons. They ensured that the torpedo dropped without roll.
• This allowed the torpedo’s horizontal rudders to be used to pitch the nose up immediately on impact with the water. This would not be possible if the torpedo were rolled when it hit the water.
• This reduced the initial plunge.
• It allowed the aircraft to drop their torpedoes from an altitude of 66 feet (20 m) and at a speed of 185 mph (160 kt, 300 km/h).
• The British used an entirely different system for their shallow-water attack at Taranto Harbor a year earlier.
• They attached a wire to the torpedo’s nose. Playing out from a drum attached to the airplane, the wire exerted upward resistance on the nose, keeping it from rotating downward too steeply."

Cavite Naval Base could host medium sized warships but lacked the facilities to maintain them.

You ignored using bombs. Anyway, don't you believe bombs were the major cause of ships getting sunk or heavily damaged? And don't be surly on this.

Most of the bombs were misses. The only one that did significant damage was the one that hit Arizona. The torpedoes sank most of the ships. The IJN considered torpedoes to be the ship-killing weapons. Even in December 1941 navies disregarded the danger of horizontal bombers to ships. Actual events proved them correct.

Kaiten

Kaiten

You ned to link to the post you are answering to. Otherwise, your one-word posts are stupid. There was no Kaiten in 1941. They were suicide weapons developed in late 1944.
