Mission of Every Soldier

This is part of an article in a local paper:

"He flew B-17s, an ancestor of today's B-52 fighter jet that can fly halfway across the world to deliver its deadly cargo with robotic precision. The weapons are more advanced today, the enemy more fluid. The mission -- maintain order in the world -- remains the same. The common desire of every soldier, to do his duty, return home and bring as many of his friends as he can, hasn't changed. "

The mission of the US Military is to "maintain order in the world"?

Can someone set me straight on this? Don't soldiers take an oath to uphold the US Constitution?

Here it is:

I, (NAME), do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; and that I will obey the orders of the President of the United States and the orders of the officers appointed over me, according to regulations and the Uniform Code of Military Justice. So help me God.

This engages a soldier in a fundamental work, a human work, a divine work; to protect the citizenry from those who would threaten their liberties, their civil rights. For that I am thankful, and would incline my freeman's head to such a person; he or she who would risk life and limb to keep the Bill of Rights held up high.

More here.

In my estimation the current enemies of the US and the Constitution are the Central Bankers.

The Constitution is a document that disperses power. It breaks up the consolidation of power. It puts the maximum influence and freedom in the hands of the individual. When I hear the phrase "maintain order in the world" I hear a call for the exact opposite of what the Constitution has at its heart.

I've also wondered what happens when a soldier's orders conflict with the Constitution. For example, if a soldier is ordered to fire into a crowd of protesters. Or to search the homes of a citizen without a warrant. Or to disarm the local population.

Do you know what percent of GDP (net effort of all citizens) is spent on the military? It's 4%. Is that high? Yes, comparatively. My question is: at what percent would you say it's too much?

My current congressional representative (Jason Chaffetz) is doing a lovely job and I feel well represented. However, in his last missive he says that he believes that "Defense" should be at least 4%. That struck me as odd. So he would have no problem if the military were at 20% of GDP? What about 80%?

The Utah Republican party platform calls for a military of "sufficient" size. I read that as meaning "big enough for the job but no bigger".

Highest was WW2 by the way at 37%.

So, where are you? What percent should it be? Really, I would like to hear some responses.
