Terrorism in the US

There are quite a few examples of terrorism that have occurred in the US, especially over the last couple of decades. Some of these attacks were caused by outside sources, such as Al Qaeda, but some were also caused by US citizens, some trained by outside groups, and some who were just very anti-government and felt they needed to act on those feelings. Many of these attacks are well known, but we tend to focus more on those caused by outside groups because we as Americans don't want to think about our own people turning against us. No matter what we choose to acknowledge though, here is a list of a few well known terrorist attacks that have happened in the past couple decades: The Unabomber, The first world trade center bombing, 9/11(second world trade center bombing), and the Oklahoma city bombing. These are just a few examples of terrorism affecting us here in the United States, some of them, like the Oklahoma City bombing, caused by US nationals, and some, like 9/11, caused by outside, mostly radical muslim, groups.
