That is why the twin towers (symbol of financial capital in America) and pentagon (Representation of America's army) were attacked, not churches, synagogues, Mormon, Buddhist, Hindu temples or any other religious place.
It wasn't in the name of religion only people who can't be bothered to look deeper than the media will think that, the attack was by Islamic nationals but it wasn't about Islam.
Similar to WW2 Japan used kamikaze pilots (suiciders) similar to this where the "terrorists" also can be seen as kamikaze pilots, they did the same thing took their lives for a bigger loss to their opposer. Both were an act of patriotism, rage, fear and injustice. Whether you see war or not it was there it wasn't over power and control it was already brewing over the oil industry in Iraq and other middle-eastern countries.
Similar to the US vs Japan the US bombed Japan out of fear because they believed they may lose. If the US was to lose they would have felt the same rage, fear, injustice and with their patriotism decided to nuke Japan. It was a cowardly act no matter how you look at it, the first one was an act of fear and the second was just a cowardly act. They killed thousands of people and affected the lives of hundreds of thousands and many in the US still claim 9/11 to be the worst attack in human history.
Don't say its an attack over religion because it isn't. It was an act in a raging war which had been going on where the media couldn't exploit it.
Same as it was for Japan and America
Also note this down pearl harbour attacked soldiers who were armed and had volunteered for the war and knew the consequences of doing so whereas the nuke hit civilians not soldiers who at the time weren't all for the war and had never signed up their lives for their country.
