It was, at least, a very probable target, no matter whether they investigated Taranto or not.

And it was not properly defended (too few patrol airplanes - repeatedly pointed out by Kimmel, also during the subsequent investigation, I believe).

Nor was the base alerted when HQ intercepted the Japanese message, afaik. I have read about something 15 hours between the intercept and the attack.
Is it true that Marshall used a commercial radio to alarm Pearl, without any urgency, instead of using a military channel? I am asking, not accusing.

I don´t doubt that the subject was up before, but I´m new here and would like to hear a qualified voice on this.

It looks like a setup to me. If so, why was FDR so keen on entering the war against 80% of population (last pre-war Gallup with a clear question yes/no to war was in July ´41. Several months earlier the % against was 95)?
