I am writing a paper for school over winter break and this is one of the question i have to answer I really cant find anything on line so any help you could give would be great.

what measures would it take to destroy and/or disrupt the infrastructure of our goverment?

The "infrastructure" of government consists of the federal and state constitutions, the elected and appointed officials, and the buildings (such as the White House, federal, state and local offices and military bases) where government employees work. To destroy all that would require a revolution or a World War. Is that really what you want?

The alternative to government is anarchy: the absence of law and order, such as you have in Somalia, Zimbabwe and parts of Mexico. I personally do not believe that is a preferable alternative.
