To understand Afghanistan’s current political situation you have to look back at the historical circumstances the country has been under.
Prior to the Soviet invasion of 1979, Afghanistan for the most part was at peace and in the 1950s going through modernization and westernization due to King Zahir Shah.
In 1979, the soviet union invaded Afghanistan and leveled the country. Destroying almost everything in its path. Which soon gave rise to the Taliban where they seized control of the country.
