Argentine President Javier Milei reignited the decades-old dispute with the United Kingdom over the Falkland Islands this week, announcing sanctions against companies linked to oil exploration off the archipelago and a decree to build a naval base in Tierra del Fuego.
Milei did not propose military action, but said Argentina would use all the tools available to the state to advance its sovereignty claim over the islands, which Argentina calls Las Malvinas. The British government responded that its commitment to the islands is absolute and unwavering.
Echoes of 1982
The current standoff differs sharply from the situation in 1982, when Argentina invaded the islands and Britain sent a military force to retake them. Argentina held a numerical advantage in aircraft and troops deployed at the time, but training and logistical problems undermined its performance during the conflict, in which 907 people died.
More than 40 years later, available data points to a clear British military advantage.
Military capabilities compared
According to the Atlas index, the United Kingdom ranks eighth among the world's leading military powers, while Argentina sits in 52nd place. The index gives Britain a score of 52.5 out of 100, compared with 29.4 for Argentina.
One of the starkest differences is in military spending. The UK allocates roughly 62 billion pounds to defence, compared with about 2.95 billion for Argentina. Britain also fields around 183,000 active military personnel, against 103,000 in Argentina.
The gap widens further in air power. Argentina has between 215 and 241 military aircraft, but only 32 of them are combat jets. The UK operates 945 aircraft in total, including 171 combat jets such as the Eurofighter Typhoon and the F-35B.
At sea, Britain has two aircraft carriers along with destroyers, frigates and submarines. Argentina has no aircraft carriers and maintains a much smaller fleet.
Nuclear capability marks another gap. The UK holds an estimated arsenal of 225 nuclear warheads and operates four ballistic missile submarines. Argentina has no nuclear weapons.
Argentina's modernisation push
The Argentine government has begun modernising its armed forces, with F-16 fighter jets among its main acquisitions and a plan to bring in 235 Stryker armoured vehicles.
Despite the disparity in capabilities, any potential British military operation would have to contend with the geographic distance separating the UK from the islands. Argentina's mainland territory lies far closer to the archipelago.
What comes next
For now, the dispute remains confined to the political, diplomatic and economic sphere. The UK maintains that sovereignty over the islands belongs to Britain and that the right of the islands' inhabitants to self-determination must be respected.
