Think about it this way.
Since 2000 we have QUADRUPLED border patrol protection. Yet, to no avail. The US needs to focus time, money, and effort on domestic affairs that we have control over(i.e. poverty). The US takes great pride in sticking our nose in inter-domestic affairs. Whereas I believe we will have a greater impact dealing with crime, poverty, and things like that on the homefront.
forget, I'm tired.
