The Ends Justifies The Means.

A Prince... Must Learn From The Fox And The Lion... One Must Be A Fox In Order To Recognize Traps, And A Lion To Frighten Off Wolves. Those Who Act Simply As Lions Are Stupid. So It Follows That A Prudent Ruler Cannot, And Must Not, Honour His Word When It Places Him At A Disadvantage And When The Reasons For Which He Made His Promise No Longer Exist.

War Is Just When It Is Necessary; Arms Are Permissible When There Is No Hope Except In Arms.

From The Latter He Is Defended By Being Well Armed And Having Good Allies, And If He Is Well Armed He Will Have Good Friends, And Affairs Will Always Remain Quiet Within When They Are Quiet Without, Unless They Should Have Been Already Disturbed By Conspiracy; And Even Should Affairs Outside Be Disturbed, If He Has Carried Out His Preparations And Has Lived As I Have Said, As Long As He Does Not Despair, He Will Resist Every Attack.

The Prince Who Relies Upon Their Words, Without Having Otherwise Provided For His Security, Is Ruined; For Friendships That Are Won By Awards, And Not By Greatness And Nobility Of Soul, Although Deserved, Yet Are Not Real, And Cannot Be Depended Upon In Time Of Adversity.

A Prince Must Be Prudent Enough To Know How To Escape The Bad Reputation Of Those Vices That Would Lose The State For Him, And Must Protect Himself From Those That Will Not Lose It For Him, If This Is Possible; But If He Cannot, He Need Not Concern Himself Unduly If He Ignores These Less Serious Vices.
