Falklands strike capability was also political

Could Britain have struck the Argentine mainland during the Falklands War?

Britain had some engineering capability to strike at range, but political consequences and the limited military payoff made that very different from a practical option.

The Black Buck raids required a large effort for their direct military effect, although their psychological and information value could be substantial. Britain had some technical ability to strike the Argentine mainland. Bombing Buenos Aires, however, is judged likely to have cost important American support. The comparison treats the two sides' technology as broadly similar while acknowledging Argentina's lack of a comparable heavy-bomber force. Technical reach and a politically usable operation were different questions.
