Keith,
Revisionism is fine, so, why did Thatcher manage to close Polls again with the Foot Labour Party somewhat before the Falkland's kicked off?

Well, and lets get real here. The SDP did rip away support from Foot, however, and as underscored, we had genuine CIA involvement in British Politics, and for all of us who lived through the monstering of Foot by the MSM, that's print, TV and radio, let us not forget there was no internet, that all in the UK got their information from the three sources I've mentioned and that the blitz against Foot was extreme.

Obviously reactionary forces remained within the Party after the SDP split, but unlike Corbyn, Foot desired to the lead the Party and was competent in handling his enemy within, i.e., Foot was not destroyed by the Party machinery, like Corbyn, he was destroyed by the Media, the establishment and the UK's surprise success in the Falkland's, which Thatcher milked for all it was worth.

Its also must be noted, as the historical record shows, that the UK was actually close to losing the Falkland's war, and that if had not been for US support via Chile history may well be very different.
