A part of rhetoric [http://en.wikipedia.org/wiki/Rhetoric] is to manipulate the facts to sway the viewers’ opinion.

HAARP problem in assignment 12.
A part of rhetoric [10] is to manipulate the facts to sway the viewers’ opinion. You need to recognize this manipulation in the context of science and engineering (not only in politics). One example in this video is that interruptions of communications in a nuclear war are the primary objective of HAARP.
Indeed nuclear explosions generating an electromagnetic pulse (EMP) do disrupt communications by creating gamma rays whose Compton electrons spiral around the Earth’s field lines thereby producing a huge EMP (large enough to fuse 300 street lights 1300 km away). Please see the following references [11] and [12]
However, HAARP is not a nuclear weapon. Yet that doesn’t stop the authors of the video from making that false connection. Here are more reliable descriptions of HAARP along with a discussion of conspiracy theories associated with it.
Other manipulations of the facts are that the Earth’s rotation rate will be dramatically affected. It is easy to calculate the energy required to do this and compare it with the electromagnetic energy that can be generated.
Just like in the applets you need to think critically about the information you find. Here are some resources
-the effects of HAARP [13]
-HAARP on wikipedia [14]
