In her book "Drone Warfare: Killing by Remote Control", the co-founder of the peace group CODEPINK and the international human rights organisation Global Exchange delves into the new warfare system affecting the Indian subcontinent, specially Pakistan and Afghanistan.
"Drone Warfare" looks at the growing menace of robotic warfare, with an extensive analysis of who is producing the drones, where they are being used, who 'pilots' these unmanned planes, who are the victims, and what are the legal and moral implications.
"In reality," writes Benjamin, "the assassinations the US is carrying out via drones will come back to haunt it when others start doing the same thing - to the Americans."
Opposing the use of drones, she writes, "We need a vigorous debate and activism around a technology like drones that has a profound impact on our reputation, the ethical foundations of our society, the lives of innocent people, and ultimately, our security as a nation."

Though she feels not all uses of unmanned aircraft are bad, she adds "but what are fuelling the drone boom are neither scientific missions nor creative activists, but state-sponsored assassinations and semi-covert wars".
Environmental, human rights and even protest groups are starting to use drones. Drones were used after the earthquake in Japan to observe radiation levels at the Fukushima nuclear plant.
They were used in Australia to inspect the state of wildlife after a massive flood. They have great potential to help firefighters by hovering over swaths of burning forests. Benjamim, however, says that drones now under development in research centres all over the country are designed to be more lethal, have greater autonomy, stay airborne for longer periods and have a more precise, broader vision of the battlefield.
