Last Saturday, Americans and others across the world came together to remember the horrific 9/11 attacks. In the evening, two bright blue lights blazed in New York 👆, representing the Twin Towers and memorializing a day that changed the world.
Changed the world?
#1 War on terror started. After the 9/11 attacks, the US invaded Afghanistan in retaliation as it helped to hide Bin Laden – the mastermind of 9/11. The US only withdrew a few weeks ago – marking the longest war in US history. 👉 Read Squirrypedia: the formal end of the War in Afghanistan.
#2 Our air travel irreversibly changed
Do you know that only less than 10% of checked bags were screened before 9/11? Now, travel is much more strict, with metal detectors and scanners everywhere.
- The US developed the Transportation Security Administration in response to 9/11 to improve airport security, and it’s a behemoth now with a budget of USD 8 bln.
#3 Satellite tech also improved significantly📡
The quality of satellite images also improved with time, and satellite tech also played an important role in the War on Terror.
- The US military used satellites to locate Osama Bin Laden, the mastermind of 9/11.
#4 Wall Street boosted its defenses
After the attacks, the US stock market shut down for nearly a week. Since then, shutdowns have been rare as much of trading is electronic, occurring in tightly secured data centers in New Jersey. (So the threat nowadays is cyberattacks?🤔)
- Regulations in the mid-2000s also allowed multiple stock exchanges to act as backups in case one of them went down.
The impact of 9/11 is far-reaching. It’s a day that shocked the world, and a day that forever changed it.
