What was the idea behind the cult of the offensive?

The "cult of the offensive" was a military doctrine that emerged in the early 20th century, emphasizing the belief that aggressive offense was the key to victory in warfare. It posited that taking the initiative and launching bold attacks could achieve decisive outcomes, often disregarding the defensive capabilities of the enemy. This mindset influenced military strategies during World War I, leading to costly offensives despite the advent of modern weaponry that favored defensive tactics. Ultimately, the doctrine contributed to high casualties and stalemates, highlighting the disconnect between theory and the realities of trench warfare.
