Argentina was able to acquire over twenty Nasher fighter jets from Israel in 1982, the year of the Falklands war, with more Israeli weapons and supplies secretly transferred through Peru. 

It also used Israeli-supplied Skyhawk jets to sink four British warships, including the Sir Galahad, which resulted in the deaths of 48 soldiers.

Declassified files now reveal how Israel repeatedly misled the UK government about its military support to Argentina, provoking a diplomatic crisis between both countries.
