Afghanistan is a mess.
It is a mess because of over forty years of interventions.
Every group that we have fought there – al-Qaeda, ISIS and the Taliban – was created and nurtured by the Pentagon and the “intelligence community” at some point or another. The same imperialists have made the same mess in Syria, Iraq, Yemen and Libya with the same policies. We created the “terrorists” who we fought in the “War on Terror” in order to grift off the American taxpayer.
Note: ISIS has been reactivated for the purpose of thwarting the withdrawal from Afghanistan. The suicide bombing also blew up Taliban guards at the Kabul airport.
