How many terrorist attacks have been there in the US since 9/11?

Terrorism was not something new to Americans but 9/11 brought woke the nation up to the threat in a way never felt before putting the nation on high alert.

Terrorism was no something new to Americans but 9/11 brought woke the nation up to the threat in a way never felt before putting the nation on high alert.

The terrorist attack on 11 September 2001 carried out by Al-Qaeda wasn’t the group’s first attempt to cause harm to the US and its citizens. Nor was it the first major terrorist attack commited on US soil.

But the images from that day woke the US public up to the threat of violent extremists and launched the US on a campaign to fight terrorism around the world to prevent another such tragedy from happening again.

Terrorism prior to 9/11 in the US

The US has experienced numerous violent episodes since its founding as different groups clashed over race, religion or an ideology. The 20th anniversary in 2021 of the 9/11 attacks, the largest terrorist attack carried out on US soil in its history, coinsides with the year of the 100th anniversary of the largest race massacre in Tulsa, Oklahoma, when mobs of white residents attacked what was know as the “Black Wall Street”, which occured over two days 31 May to 1 June 1921.

Al-Qaeda tried to bring down the World Trade Center Towers eight years before the 9/11 attack were carried out. In 1993 a group of terrorists detonated a truck bomb under the North Tower with the intention of causing it to fall into the South Tower. The resulting explosion killed six people and injured over a thousand more but failed to bring down either tower.

Homegrown terrorists would use a similar method to attack the Alfred P. Murrah Federal Building in downtown Oklahoma City, Oklahoma. Timothy McVeigh and Terry Nichols, anti-government extremists, detonated a truck bomb on 19 April, 1995 in front of the building which resulted in the death of at least 168 people, injured more than 680 others.

Terrorism in the US after 9/11

The terrorist attack on 9/11, 20 years on, is still firmly embedded in the memories of Americans who are old enough to remember. 93 percent of those 30 and older recall exactly where they were on 11 September according to a Pew survey. A vast majority of Americans also consider the events of that day as the most consequential historical event in their lifetime. Over the two decades since those attacks “defending the country from future terrorist attacks” has been at or near the top of Americans priorities.

There has not been a 9/11 scale terrorist attack in the US since 2001 but the nation has twarted several attempts and experienced grief from smaller scale attacks. Some of the plots came from abroad but many others were home grown from extremists carried out in the name of Islam, others based on race or political extremism.
