Would Thatcher have lost without the Falklands War?

Without the Falklands War, would Margaret Thatcher probably have lost the next general election?

She was already on course to win, while the Falklands victory strengthened and cemented that advantage.

The viewer suggests that a carrier-rich alternate history might prevent the Falklands War and thereby cost Margaret Thatcher the following election. The answer is that she was already on course to win before the conflict, although the victory cemented her position. That outlook is attributed partly to the weakness and division of the opposition she faced. The war should therefore not be treated as the sole cause of the 1983 result when changing one branch of the naval counterfactual.
