There has never been a time in the past 250 years when the American military has been needed (at least not in cases in which it has actually acted).
American revolution, Franco-American War, War of 1812, Mexican-American war, the marines that provided security for the Pony Express, WWII, the rescue of medical students on Grenada, and the fact that providing no defense at all is the same as asking to be attacked and oppressed by foreign powers. You could argue about the other wars and conflicts in which we were engaged, but these were all undeniably for the good of our country.
What is this about John the Baptist?
And the soldiers likewise demanded of him, saying, And what shall we do? And he said unto them, Do violence to no man, neither accuse any falsely; and be content with your wages.
The word "do violence" refers to needlessly harassing and intimidating people, not any actions that might necesssarily be required in the line of service.
Nor am I condemning military service in general, nor was that implied by my post. What was really implied by my post was American military service, and that is precisely what I was intending.
One's agreement or disagreement with the motives of our politicians doesn't change the need for our nation to provide for it's defense.
