I would say that I have been consistent in my broad view of how American power should be deployed, and the view that we underestimate our power when we restrict it to just our military power. We shortchange our influence and our ability to shape events when that's the only tool we think we have in the toolbox.
The essential factor of military success is speed, that is taking advantage of others' unpreparedness or lack of foresight, their failure to catch up, going by routes they do not expect, attacking where they are not on guard. This you cannot accomplish with hesitation.
Whoever is first in the field and awaits the coming of the enemy, will be fresh for the fight; whoever is second in the field and has to hasten to battle will arrive exhausted.
So while I will never minimize the costs involved in military action, I am convinced that a failure to act in Libya would have carried a far greater price for America.
To this military attitude of the soul we give the name of Heroism... It is a self-trust which slights the restraints of prudence, in the plenitude of its energy and power to repair the harms it may suffer. The hero is a mind of such balance that no disturbances can shake his will.
All the armies of Europe, Asia and Africa combined, with all the treasure of the earth (our own excepted) in their military chest; with a Buonaparte for a commander, could not by force, take a drink from the Ohio, or make a track on the Blue Ridge, in a trial of a thousand years.
In Iraq and Syria, American leadership - including our military power - is stopping ISIL's advance, instead of getting dragged into another ground war in the Middle East, we are leading a broad coalition, including Arab nations, to degrade and ultimately destroy this terrorist group.
