Was the weapon necessary at all? This 'weapon' destroyed Afghanistan completely. Communist Afghanistan was going on perfectly until extremists trained by this 'weapon' started to cause chaos in Afghanistan. Then they were forced to call in Soviets for help. Soviets withdrew in 1988,but what happened after that? This socalled "weapon" backfired heavily. Civil war started and completely destroyed Afghanistan. Taliban won, came to power, destroyed arts, science, education and aesthetics completely. Afghanistan went down rat hole. Now it is the Americans trying to control these 'weapons'. Wonder what will happen next!
This particular 'weapon' has also caused 100000 deaths in Afghanistan, tens of thousands of deaths in Chechnya, 500000 deaths in Iraq (sectarian war), 60000 deaths in Libya, tens of thousands now in Syria, sectarian war in Yemen.
This 'weapon caused so many deaths in the modern world, completely destroyed image of Islam worldwide. And most of it originates from a particular country I don't have to name.
