(I really dislike the word "conspiracy" because it ridicules the positive aspects of questioning and criticising. And that is wrong.)
Yes, as we all know, history tends to repeat itself.
I'll try to be very frank:
A new era began with 9/11 and the main point of this thread is to try to link two historical incidents to it.
Pearl Harbour 1941
How in the world can one link 9/11 to Pearl Harbour?
Well, in both cases, the leaders of the attacked nation (USA) knew about the attack prior to its launch. Both Bush and Roosevelt knew and lied about the knowledge. (The difference is, Roosevelt admitted).
Why would they do this?
There are many reasons why such a thing would pay off in war, and one is the Japanese domination in the Far East Asia, something the US couldn't tolerate.
Please take a look at the interesting article:

German Reichstag (1933
There are many indications that the Germans torched their own Reichstag to create scapegoats and eventuality reasons to start a war. George Bush knew that the attacks were impending, yet the USAF wasn't permitted to act.
And the interesting article:

Now, the Americans didn't fly the planes into the towers themselves (or did they?), but their government prevented action to stop it.
Why would they do this?
I believe the US High-Ups felt the installation of Saddam (so that he could be dethroned later) and 3000 Americans killed in the 9/11 was definitely worth the oil-war. It's a brutal and crazy thought, I know.
Can one link those historical happenings to 9/11?
