Hyon Yong-chol vs John Arbuthnot Fisher

Hyon Yong-chol was appointed Minister of the People's Armed Forces (Defense Minister) of North Korea in 2012 by Kim Jong-un. He oversaw the military's operations and modernization efforts during a period of heightened tensions with South Korea and the United States.

Hyon Yong-chol was demoted from his position as Minister of the People's Armed Forces in 2014, reportedly due to poor performance or political infighting. He was replaced by Pak Yong-sik, but later reinstated briefly before his execution.

Hyon Yong-chol was reportedly executed in April 2015 by anti-aircraft gun fire, according to South Korean intelligence. The execution was allegedly ordered by Kim Jong-un for disloyalty, including falling asleep during a military event and challenging the leader's authority.

As First Sea Lord, Fisher implemented major reforms of the Royal Navy. He scrapped obsolete ships, concentrated the fleet in home waters, improved training, and introduced new technologies like submarines and destroyers. These reforms modernized the Navy.

As First Sea Lord, Fisher championed the construction of HMS Dreadnought, a revolutionary battleship. Its all-big-gun armament and turbine propulsion made it the most powerful warship of its time, triggering a naval arms race with Germany.

Fisher resigned as First Sea Lord in protest over the Dardanelles campaign, which he opposed. His resignation caused a political crisis and weakened the government of H.H. Asquith. He was replaced by Henry Jackson.
