As a Result of the Global Burdens the United States

As a result of the global burdens the United States assumed after the Second World War, how did the federal government change?

A) Although it grew larger in general, most power remained with Congress, as Congress came to assert its authority far more frequently such as by making the decision to declare war in Korea.
B) It became much smaller in response to conservatives' criticisms that big government represented a threat to liberty in America and that taxes funding the federal government were too high.
C) Although it grew smaller at the federal level, local and state governments swelled as they took on additional responsibilities, including those that had previously fallen under federal agencies.
D) It became smaller due to pressure from the disenchanted American public after people soon realized that the paranoia brought by the Red Scare was in many ways politically motivated.
E) It became larger, more powerful, and more secretive, in part due to the actions of both major political parties and the lobbying efforts of the military-industrial complex.
