I'm thinking the terrorist attack would look like this.
- Occurs on December 2nd, 2015. The same day as OTL San Bernardino attacks
- Multiple attacks across the United States happen near simultaneously.
- Omar Mateen enters the Pulse Nightclub with a second shooter, both wearing body armor. They precede to kill 110 people due to attacking at a busier time and a second shooter being present.
- The San Bernardino attack happens on schedule, however explosive left behind by them detonate and kill and injure several first respondents. Together they kill around 24 people.
- At a sports arena in Virginia a suicide bomb goes off in a crowd, causing panic and killing half a dozen people. Once people flee the stadium, four more bombers join the crowd with three of them detonating while completely surrounded by people. All together 79 people are killed, either through the explosions or by being trampled.
- In the New York Subway almost a dozen bombings happen along the line, similar to the 2004 Madrid train bombings. 251 are killed in the bombings.
- On the streets of Chicago two large trucks leave the streets and begins mowing down pedestrians on the sidewalks. Together the two drivers manage to kill 50 and 62 people, bring their total killcount to 112.
- During a Christmas Parade, several men open fire with automatic rifles and detonate bombs. Together they manage to kill 178 people before they are killed or retreat. This happens in Austin, Texas.(Not sure if they have a Christmas Parade December 2nd there.)
- At two nightclubs in Las Vegas, shooters open fire before detonating suicide bombs. In combination they manage to kill 54 people.
- At the Massachusetts Institute of Technology a shooter opens fire in one of the dorms, killing eight students.
- All of these attacks combined kills 816 Americans while wounding thousands of others.
- They find that these attacks were perpetrated by both homegrown Islamic terrorists and foreign nationals who traveled to the United States.
- They found they most shooters gained access to their weapons through legal and semi-legal channels.(Such as bringing weapons across state lines.)
- Through investigation they found that all attackers had links to the ISI
How does the United States people and public react to this, how does this effect the United States election and the foreign policy of Barrack Obama. Would the U.S become more involved in Iraq or would the Iran Nuclear Deal fail to pass.
With that kind of widespread and bloody attack against lots of soft targets ..... well ..... I don't think the words really exist to describe the blood-mad rage that would grip the US populace. The only thing that would be worse is nuclear terrorism.
Probable responses:
a huge gun control push, with the high probability of a national gun registry for ALL firearms
A massive wave of hate-crimes against Muslims: mosques being bombed and set on fire, Muslims beaten by mobs in public; essentially a huge such wave of attacks that would overwhelm authorities, requiring National Guard units in many states to restore order
an absolutely murderous bombing campaign against all ISIS held population centers; the prevailing opinion among many Americans being " there are no innocent Muslims in ISIS territory. If you don't rise up and throw them out, you are as responsible for their actions as they are." ; so, tens of thousands killed in just a few days
serious debate in the US as to whether or not limited use of nuclear weapons against terrorist held areas would serve as a huge exclamation point on America's fury
federalization of all National Guard units in preparation to invade Syria
PLEASE NOTE: I am not personally endorsing ( or not endorsing) these possibilities. Most Muslims would never even think of doing something like these attacks. I am simply giving my honest opinion of what I believe would be the indescribable rage in the US, and the things it would lead to.
