Final answer:
The irony lies in the historical fact that England was one of the world's largest imperial powers, dominating vast territories globally during the 19th century, before facing decline due to the rise of new powers.
Step-by-step explanation:
The statement that England has never reached the status of a world imperial power is ironic given England's history of imperial dominance. During the 19th century, the British Empire was unrivaled, controlling extensive territories globally and commanding the seas with its Royal Navy. Strategically placed colonies and advancements such as the Industrial Revolution and telegraph cables were instrumental in establishing a global British Peace.
However, geopolitical shifts and the rise of other powers, such as Germany and the United States, brought an end to British pre-eminence, marking an era of imperial decline after the 19th century.
