Look back to the 1970's and Afghanistan was a relatively peaceful country. Foreign super powers were busily working at destroying any attempt at peace though. Russia went into Afghanistan in 1979, allegedly at the request of the country's leaders, and the U.S. worked at causing Russia problems.
It was a similar scenario to the Ukraine with Afghanistan allegedly wanting to cut ties with Russia.
The U.S. sent in special agents to train terrorists, in an effort to outfox and hit Russia hard.
That of course spectacularly backfired on America. The trained insurgents, the Mujahideen, became the Taliban and turned on their western puppet masters, big style.
But look back to earlier times and Great Britain and Russia have flexed colonial muscles over the country.
"1838-42 - British forces invade, install King Shah Shujah. He is assassinated in 1842. British and Indian troops are massacred during retreat from Kabul."
Yes we all like to mix it up, or rather we did during our colonial years. Should that still be happening in the 21st Century?
Peace is possible in any country but it needs the will of the majority of people, time, a lot of luck and the opportunity for the people to work out their own destiny, without foreign interference.
