The Eternal Cycle Continues...
Drones kill people, without trial or in some cases without any evidence of wrong doing. Their family members get angry and seek revenge. Farmer waiting at the side of the road waiting for his cousin to pick him up, drone pilot see a suspected ISIS member planting a road side bomb. *blam* Wedding party in progress, drone pilot sees suspected terrorist gathering. *blam*
Terror levels rise when those folks get tired of the murder and start shooting back. More drones are fielded to combat the rise in hostilities, etc. etc.
In the meantime, corporations get mega-wealthy supplying flying instruments of death, while normal people pay the price.
The Americans kill more people annually than all terrorist organizations combined, and by a wide margin. Arrogance tempered with ignorance and funded with greed.
