September 11th is American Patriot Day.
This day is held every year as a memorial day to commemorate the victims of the “September 11 attacks” that occurred on this day in 2001.
These are four simultaneous terrorisms carried out by the Islamic extremist organization “Al Qaeda”.
It was a catastrophe that killed 2,996 innocent people and injured more than 6,000.
In response, the USA and the Volunteer Union have declared retaliation against the terrorist organizations and the countries and regions that supported them.
As a result, it triggered the later Afghanistan conflict and Iraq war.”
