About Cuba

Cuba is an island nation located in the Caribbean Sea, just south of the United States. It has a rich history, including being a Spanish colony, and has undergone significant political and economic changes over the course of its existence.

For much of the 20th century, Cuba was ruled by Fidel Castro, who took power in a revolution in 1959. Under Castro, Cuba adopted a communist form of government and formed close ties with the Soviet Union. The country faced economic difficulties and a trade embargo from the United States, which further isolated it from the rest of the world.

In recent years, Cuba has undergone some economic and political reforms, and relations with the United States have improved somewhat. However, the country still faces significant challenges, including a struggling economy, a lack of political freedom, and a lack of access to modern technology.

Geography & terrain

The largest Caribbean island, mostly flat to rolling terrain with the Sierra Maestra mountains rising in the southeast. Climate is tropical, moderated by trade winds, with a hurricane season. Entirely coastline, as an island nation. Its island geography has long made large-scale overland invasion impossible, forcing any approach to come by sea or air, while the mountainous southeast has offered further natural refuge.

Battle narrative

Initial phase

With both the bigger war chest and the stronger air force, United Kingdom is well placed to seize the initiative early, striking key military and infrastructure targets first.

Force composition

Cuba can also call on significantly more personnel, counting both active-duty and reserve forces. United Kingdom's advantage extends to naval power as well.

Ground campaign

Cuba's terrain could make a rapid ground campaign difficult: Its island geography has long made large-scale overland invasion impossible, forcing any approach to come by sea or air, while the mountainous southeast has offered further natural refuge. Havana would likely be a focal point of the campaign: The capital and largest port, hosting the main naval facilities and serving as the country's political and logistical center. United Kingdom's terrain could make a rapid ground campaign difficult: An island nation, which has been its main defense for most of its history — the last successful foreign invasion was in 1066. Strait of Dover would likely be a focal point of the campaign: The narrowest point of the English Channel, a chokepoint for shipping between the North Sea and the Atlantic and historically Britain's first line of coastal defense. United Kingdom's larger population could also support a prolonged resistance.

Prolonged conflict

United Kingdom's stronger economy could help sustain military operations in a prolonged conflict. United Kingdom also devotes a larger share of its economy to defense (about 2.0% of GDP), a more militarized posture that could be easier to sustain over time. Occupying Cuba outright would likely prove costly given its terrain.

Overall assessment

United Kingdom would be more likely to prevail in this matchup, with an estimated 74.1% probability of winning. Achieving a decisive victory over Cuba — let alone occupying it — would likely be more difficult than that headline number suggests.
