The economic case for deterrence is that funding ships which prevent war costs less than fighting the war and having to build the ships anyway. Even with four larger British carriers ordered, the complete force would not enter service until 1987. The scenario assumes that diplomatic neglect continues, including failures to heed the governor and the ambassador in Buenos Aires. More naval capability therefore does not guarantee that the Falklands War is prevented.

Why larger carriers might not prevent the Falklands War
Carrier delivery dates and diplomatic decisions leave room for war even with a larger British fleet on order.
