The Constitution's preamble contains the words "provide for the common defense". Whether you like it or not, every citizen has a duty to defend the country in order to establish a just, humane, and democratic society and to safeguard the nation's sovereignty.
But as you may be asking, we already have the forces, so how does this actually benefit the United States?
Short answer is to defend the nation! Long answer is that only capable citizens are required to enlist when a war threatens the nation's liberty in order to have a stronger defense against the threats, even though the government's primary duty is to defend the country against foreign adversaries.
Is the preamble obligating the citizens to defend the nation? Yes! The preamble states that the United States of America's sovereign American people have the duty to obey the Constitution, which is the highest law of the land.
