SLL: your last para is so true. 1945-50 Foreign Secretary Ernest Bevin is interred in the Abbey under the epitaph Statesman: he was the father of NATO, whose purpose was to keep the Americans In, the Russians Out and the Germans Down. FDR, then Truman intended to bring the boys home within 2 years of VE Day. The core of NATO - all for one, one for all - is historical anathema to US - entanglement in foreign wars; that entanglement, and extracting $-gazillions in Marshall Aid, 1947-50 and under MDAP/MSP/MWDP, 1949-63, were sublime achievements, central to UK's recovery from the 20th.Century European Civil War. Helping US in (most of) its recent Expeditions is no more than our duty. Wilson's great achievement was to sustain that relationship despite declining LBJ's desire that UK stand with Oz, Phil, et al in Vietnam - even a band of bagpipers would do. That was not inspired from his "Moscow handlers", disappointed that UK had less Vietnam strife than did, say, France.
Wilson-the-stooge was singularly counter-productive for his "paymasters", which is why this conspiracy is piffle. A much, much better one involves US Security Advisor, Polish Zbig, who has claimed that First Afghanistan - the Sovs' one from 1979 - was deliberately fomented by (him), with the successful objective of eroding the stature of Military and Party in USSR, to the point of revulsion and rejection by the governed, who saw neither guns nor butter.
