Wilson supported the US in Viet Nam but played a line between the majority of the Labour Party being against any such support, voting against it at Labour conferences, and huge demonstrations against the War and any British involvement in it / and refusing US requests for UK armed support. He did however covertly send weapons including napalm to US forces, trained S.Vietnamese forces in Malaysia, and US special forces, and from Hong Kong intercepted military messages for the US. All this was not publicly known at the time but rumoured, suspected. He also tried to persuade the US from bombing and escalating the war, and negotiated to wind it down.
As the post below yours (from Oslo) refers, although there was no British military involvement in Vietnam, there were a number of other ways in which the British were involved.
This is quite an interesting read on Thatcher from a Guardian journalist (his credibility undermined somewhat by his final paragraph): https://www.theguardian.com/commentisfree/2018/jan/01/margaret-thatcher-respect-labour-tory
The Falklands War was sparked by Argentina invading!! Galtieri was pandering to his electorate. It's quite a stretch to blame Thatcher for the invasion. The subsequent war and the way she ran it certainly bought her a lot of credit here, but Argentina badly underestimated our response. Their Ambassador was interviewed on the radio and admitted that they didn't expect us to send a task force. Her popularity was born out of that victory, but Argentina caused the war.
I would have thought after your disastrous yesterday you might not have made yourself look a t22t today? You have outdone yourself. At least the person who tweeted that, read the story. You just jumped on the bandwagon you headline grabber.
