WI: a )/11 equivalent or worse attack committed against USby a non-Islamist terrorist

What would be the geopolitical and social consequences of a devastating attack on the US by a group of perpetrators who are not driven by Islamist ideology?

Options I can think of at first:
- hard leftist/anti-imperialist groups
- Neo- Nazis
- Japanese or Korean nationalists with anti-American standpoints
etc.

How would the American response play out?

(Mods- please edit title: I meant 9/11.
 
Right Wing militia types are the obvious ones. They don't tend to go in for suicide bombings though, so the actual mechanism would likely be different.

OP, you can edit the title by double clicking on it in the After 1900 List

Oklahoma on steroids will be focused on Federal Offices, not the WTC, and would probably be a car bomb, similar to the 1993 WTC Bombing, and one that right wingers would see as being the oppressive core of the nation. McVeigh's criterion for his targets was a building containing Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), the Federal Bureau of Investigation (FBI), or the Drug Enforcement Administration (DEA), so we can assume that out RWT's will do something the same.

J. Edgar Hoover Building is built to withstand a bomb. Post-Oklahoma, DEA Headquarters were given measures that turned HQ into a fort. ATF is along the same lines. So where would this bomb be? Immediate answer is the Treasury Building, which manages all these agencies.

There's also possibly the IRS or the Bureau of Land Management if they were Cliven Bundy types.
 
There was several 'Communist' extremist groups in Eurpoe in the 70s and 80s

Perhaps a group once active in the US having gone to ground after the collapse of the USSR.

Information gleaned during the effective collapse of the Russian KGB results in dozens of 'inactive' deep cover members of these organsiations being procecuted during the late 90s forcing the remnants who were not caught or who managed to evade the 'net' going deeper into hiding and a certain number of this group decide to seek revenge on the USA for what they see as its part in the collapse of the USSR

Perhaps said remnent group seeing the damage - particularly cost - that the city centre bombings had caused by the IRA city centre and docklands bombings in the UK during the 90s do the same thing but on a larger scale in Wall street - a series of 1500 KG truck bombs but unlike the IRA give no warning (or having no previously established method of warning give an ineffective one) and this results in many 1000s of casaulties in New York city.

Could combine this with a chemical style attack on the subway (in a copy of the Tokyo style attacks) and at certain airports and even on aircraft in flight!
