Was Napoleon Really At Fault?

Here is a passage from a book I am currently reading:

Napoleon is often accused of being a quintessential warmonger, yet war was declared on him far more often than he declared it on others. France and Britain were at war for nearly half the period between the Glorious Revolution of 1688 and Waterloo, and Napoleon was only a second lieutenant when the Revolutionary Wars broke out. He launched the Peninsular War and the war against Russia in 1812 in the hope of extending the reach of his ‘Continental System,’ a misguided protectionist answer to Britain’s control of the seas, and thereby force Britain to sue for peace. It was thus Colbertian protectionism that brought him down, far more than the bloodlust and egomania of which he is so often accused.
