It’s not part of our Constitution to assume that we are the world’s policemen.

The Fourth Amendment is clear; we should be secure in our persons, houses, papers, and effects, and all warrants must have probable cause. Today the government operates largely in secret, while seeking to know everything about our private lives - without probable cause and without a warrant.

War is never economically beneficial except for those in position to profit from war expenditures.
