There is no Falklands bounce - people who say that the outcome of the Falklands conflict had no effect in 1983 just live in a different universe.
No, not no effect...just negligible.
I posted the MORI figures above. Thatcher was already on the way up before the Argentinian "scientists" set foot on South Georgia, let alone the invasion of the Falklands. Which, as I said, tied in with the economy turning the corner.
The popularity bounce had gone before '82 was out.
