The former U.S. Secretary of Defense, Robert S. McNamara, was aware that there might be objections raised by the international scientific community but said in a memo to the president that such objections had not in the past been a basis for prevention of military activities considered to be in the interests of U.S. national security. The chemical weather modification program was conducted from Thailand over Cambodia, Laos, and Vietnam and allegedly sponsored by Secretary of State Henry Kissinger and CIA without the authorization of then Secretary of Defense Melvin Laird who had categorically denied to Congress that a program for modification of the weather for use as a tactical weapon even existed.
One of the biggest conspiracy theories the world has now come to know as weather modification is now conspiracy fact, as today the government's Operation Popeye from the seventies is exactly just that. This proves everything from chemtrails to HARRP is a government program for weather warfare, and was likely being used to push the globalist conspiracy theory of climate change around the world. Of course Operation Popeye can be used in warfare to drain out a climate to make it unbearable to live in.
The main source of the government's 1970 program of Operation Popeye was likely used to push the climate change agenda of the United Nations to manually warm the Earth to push the false narrative of climate change. Whatever Operation Popeye is being used for, this confirms that chemtrails and facilities like HARRP are used to manipulate the atmosphere through weather warfare and geoengineering.
