When does the government take national security too far?

It is generally agreed that the main goal of the government is to protect its citizens. However, does government sometimes use this responsibility irresponsibly?

There have been a few situations in United States history when the United States has taken the matter of securing the public too far. One was during World War II, when FDR banished thousands of Japanese Americans to concentration camps. The United States forced these Japanese American citizens into camps for "protection" of the people, preemptively striking out espionage. But these people were citizens. No background checks went into choosing who would go into these camps. While racial profiling hasn't existed to such extremes in the United States since, it does still exist. Take, for example, the selecting of Muslim/Arab looking people in airports for "random" security checks.

Also, during the Bush administration, Homeland Security was established and soon enacted some "security" measures like wire tapping and sifting through the average citizen's library records. This is taking the sake of national security past the boundaries of what is acceptable--violating the Bill of Rights and personal property.

In addition, when looking at the 2010 national security document, there were a lot of not-quite-related-to-DEFENSE-OF-THE-COUNTRY points. Obama had points about combating poverty and climate change, among other things. While they are problems, they are not external forces that we can militarily protect ourselves against. The national security plan should only contain MILITARY operations. Things that you would expect the Department of Defense, National Security Agency, and Central Intelligence Agency to get involved with (among others like the FBI and maybe State Department). Can you imagine the DoD meddling with poverty? No. Climate change? maybe, but the focus would be on spotting nukes using satellite technology and designing drones.

Obama's security document is too comprehensive. In his attempt to protect the Untied States, he's stretching his resources too thin. Obama should instead focus his "security" on one or two plans of action. Maybe this is why Obama is having trouble in his first term: he's trying to please everyone.
