Did President Obama and FEMA Create a Youth Army? Hitler-esque, Anyone?

This video is obviously advocating a theory that cannot be proven.  The concept of a FEMA Youth Army has been circulating around the Internet for a number of years during the first term of President Obama’s administration.  While not the final word by any means, the video does draw together several different things that have led to the creation of this conspiracy theory that instinctively draws parallels to Hitler.  What do you think?  Is there really a FEMA Youth Army?  If so, what is their purpose and why use young people instead of adults?  Is the government reaching out to impress its agenda on those that have not developed enough to think for themselves?
