Yes, Homeland Security should label the deterioration of America's infrastructure as a threat to national socio-economic security, because we need a good network of highways and roads in order to provide for our common defense. If people need to evacuate an area because of an attack, they need to make sure there are highways and bridges.
Yes, Homeland Security should label the deterioration of America's infrastructure as a threat to national socio-economic security. There is an undeniable link between America's infrastructure and its socio-economic security and so as our infrastructure continues to crumble, due to age, outdated technology and a general lack of up-keep, it exposes the U.S. to a kind of terrorism that could bring the country to its knees.
The amount of failures in the United States infrastructure represent very real risks to the American population. Whether it's failing roads that are causing congestion on the roads and inefficiencies in the economy or deteriorating buildings that are too risky too live in, there are real problems that constitute grave threats.
Terrorists have already demonstrated more than once that they like to target economic symbols as much as military targets. The World Trade Center was certainly not a vital element to day to day operations of the country, but they hit it not once but twice. If infrastructure is allowed to continue to deteriorate, it does impact economic security greatly and makes specific pieces of infrastructure easier for terrorists to hit.
It is not the responsibility of the Department of Homeland Security to make the determination if the deterioration of America's infrastructure poses a socio-economic threat. Homeland Security's responsibility to ensure the integrity of the physical and cyber elements of the nation's infrastructure. The socio-economic aspects, and risks, of the nation's infrastructure are the responsibility of the Congress.
