Many intelligence reports in war are contradictory; even more are false, and most are uncertain.
Carl von Clausewitz...as man under pressure tends to give in to physical and intellectual weakness, only great strength of will can lead to the objective.
Carl von ClausewitzTo discover how much of our resources must be mobilized for war, we must first examine our political aim and that of the enemy. We must gauge the strength and situation of the opposite state. We must gauge the character and abilities of its government and people and do the same in regard to our own. Finally, we must evaluate the political sympathies of other states and the effect the war may have on them.
