"Of all the enemies to public liberty war is, perhaps, the most to be dreaded because it comprises and develops the germ of every other. War is the parent of armies; from these proceed debts and taxes… known instruments for bringing the many under the domination of the few.… No nation could preserve its freedom in the midst of continual warfare." — James Madison

Eventually, all military empires fall and fail by spreading themselves too thin and spending themselves to death.

It happened in Rome.

It's happening again.

At the height of its power, even the mighty Roman Empire could not stare down a collapsing economy and a burgeoning military. Prolonged periods of war and false economic prosperity largely led to its demise. As historian Chalmers Johnson predicts:

The fate of previous democratic empires suggests that such a conflict is unsustainable and will be resolved in one of two ways. Rome attempted to keep its empire and lost its democracy. Britain chose to remain democratic and in the process let go its empire. Intentionally or not, the people of the United States already are well embarked upon the course of non-democratic empire.

The American Empire—with its endless wars waged by U.S. military servicepeople who have been reduced to little more than guns for hire: outsourced, stretched too thin, and deployed to far-flung places to police the globe—is approaching a breaking point.

War has become a huge money-making venture, and America, with its vast military empire and its incestuous relationship with a host of international defense contractors, is one of its best buyers and sellers. In fact, as Reuters reports, "[President] Trump has gone further than any of his predecessors to act as a salesman for the U.S. defense industry."

Under Trump's leadership, the U.S. military is dropping a bomb every 12 minutes.

This follows on the heels of President Obama, the so-called antiwar candidate and Nobel Peace Prize winner who waged war longer than any American president and whose targeted-drone killings resulted in at least 1.3 million lives lost to the U.S.-led war on terror.

Most recently, the Trump Administration signaled its willingness to put the lives of American troops on the line in order to guard Saudi Arabia's oil resources. Roughly 200 American troops will join the 500 troops already stationed in Saudi Arabia. That's in addition to the 60,000 U.S. troops that have been deployed throughout the Middle East for decades.

As The Washington Post points out, "The United States is now the world's largest producer — and its reliance on Saudi imports has dropped dramatically, including by 50 percent in the past two years alone."

So if we're not protecting the oil for ourselves, whose interests are we protecting?

The military industrial complex is calling the shots, of course, and profit is its primary objective.

The military-industrial complex is also the world's largest employer.
