The Nation Security Strategy created by President Obama in 2010 is described below.
National security is the safety of a nation against threat whether internal or external. National security ensures that a nation is secured against terrorism, war, or espionage.
It is the job of a president to guarantee the safety of his/her citizens against domestic or international threat.
The president can achieve this by entering into security treaties and such treaties must be approved by at least two thirds of the senate members.
