Will Illegal Immigration Ignite Civil War?

Possibly 20 million illegal immigrants reside in America. Many of which possess radical socialistic worldviews and believe much of American land belongs to Mexicans and Hispanics. Many illegals have placed States already in economic hard times into bankruptcy. The character and environment of many communities has changed due to the wave of illegal immigrants. Americans are growing tired of excuses from the federal government for not securing the border and solving these issues. Therefore, States and local governments have begun working to fix these problems the best they can. Yet, the response from the Obama Administration and Washington is one of contempt and arrogance. Declaring their intention to sue the State of Arizona and grant amnesty to illegals, is this the spark that will ignite an already volatile situation in America?
