I'm indulging in a bit of provocative lateral "what-if" thinking.
The US and Israel have started rattling sabres again this time towards Iran because they're afeared that Iran's uranium enriching programme is intended for the manufacture of nuclear warheads for missiles, so the US and Israel feel that they would be justified in a pre-emptive strike to prevent said missiles being made.
Hhmmm....then I thought, well surely the US must see the irony inherent in that logic and it isn't going to escape many people's minds that perhaps the Japanese in 1941 were also justified in their pre-emptive strike agaist Pearl Harbour to prevent themselves from being attacked by nuclear weapons. That is to say of course, if they even knew that Oppenheimer was working on them, which I doubt.
But it would be a beautiful irony wouldn't it. Either way it didn't work becasue the US as we all know dropped two A bombs on the Japanese.
And just as that attack only added to the USA's resolve to enter the war, a joint Israeli-US pre-emptive strike on Iran would only make the Iranians even more determined to wipe Israel off the face of the earth and presumably to launch attacks against the USA.
Seems to me that the US hasn't learned from the historical mistakes of others
