In this case, I found many quotes worthy of that task, so I cite the following and ask the reader's forbearance:

"Should Saddam Hussein choose confrontation, the American people can know that every measure has been taken to avoid war, and every measure will be taken to win it. Americans understand the costs of conflict because we have paid them in the past. War has no certainty, except the certainty of sacrifice." — President George W. Bush, prior to initiating Operation Iraqi Freedom, a war resulting in 4,418 U.S. military deaths

"The master class has always declared the wars; the subject class has always fought the battles." — Eugene V. Debs

"He is always stirring up some war or other, in order that the people may require a leader." — Plato, The Republic, Book VIII

"War is merely the continuation of policy by other means." — Carl von Clausewitz

"War is a racket. It always has been. It is possibly the oldest, easily the most profitable, surely the most vicious. It is the only one international in scope. It is the only one in which the profits are reckoned in dollars and the losses in lives." — Major General Smedley D. Butler, two-time Medal of Honor recipient

"War is sweet to those who have no experience of it." — Pindar

"[In war] the State once more walks, an august presence, through the imaginations of men." – Randolph Bourne, The State

"One to destroy, is murder by the law;

And gibbets keep the lifted hand in awe;

To murder thousands, takes a specious name,

War's glorious art, and gives immortal fame." — Edward Young, Love Of Fame, The Universal Passion. In Seven Characteristical Satires.

"WAR IS PEACE" — George Orwell, 1984

War is a special preoccupation of governments.  And governments, we all learn at a young age, are the foundation of civilization. Without government who would protect us from foreign and domestic threats?  Trump finds Iran a threat, as George W. Bush found Iraq under Saddam a threat.  A threat to whom?  The American people, most of whom happen to live on the other side of the Atlantic.

In today's world and for most of history, "government" means an organization with a territorial monopoly of force and is usually called a State.  It is sovereign within this territory.  To be under its jurisdiction is to grant approval of government's right to enforce its commands or laws, one of which is the demand that it be supported economically.
