A day that forever changed the world

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 ๐Ÿ‘†, 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. ๐Ÿ‘‰ Read Squirrypedia: the formal end of the War in Afghanistan.ย 

#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 itโ€™s a behemoth now with a budget of USD 8 bln.

#3 Satellite tech also improved significantly๐Ÿ“กย 

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.ย 

#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?๐Ÿค”)

  • 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. Itโ€™s a day that shocked the world, and a day that forever changed it.ย
