I've seen many times that Jupiter is angular in relevant charts (particularly lunar ingresses) for events of diplomacy; I've included that in my standard interpretations in SMA for several years. But I never checked this specific event, one mentioned simply in passing by Bradley in his original introduction of Sidereal solar and lunar ingresses.The simplicity of the demonstration is the thing to marvel at; meetings of heads of state, as with Eisenhower and Macmillan at Bermuda, for a recent example, occur when the ingresses show Jupiter right on an angular cusp at the conference place.
-- Donald Bradley, "Unveiling a New Tool," 1957
President Eisenhower invited British Prime Minister Harold Macmillan, to meet him in Bermuda (in Hamilton) March 20-24, 1957 to improve US-UK relations and discuss the Suez Crisis of the time. The goal was to demonstrate public friendship and have a meeting of minds.
The CAPSOLAR set a tone of diplomacy for the world with Moon opposite Venus and square Jupiter (all quite close).
And there it is as advertised, in the CAPLUNAR for Bermuda, Jupiter exactly on IC.
The day they convened was not so astrologically gracious (though I understand the actual meeting was most gracious), Mars was on CapQ Ascendant. But against that, CapQ Moon was within 0°34' of opposite Venus.
