Please enlarge chart image to read my study notes. You see the brutal Mars-Pluto-Saturn trio in the UN natal chart and in current transits (see center of chart). The transiting Nodal axis is involved in 2018 making things more...fated or karmic (2018 Mars conjunct 2018 SN; 1945 Saturn-Pluto = 2018 NN--see chart at bottom). Also notice that transit Uranus @1Tau39 Rx currently opposes UN natal Sun @1Sco07 (leadership). Planets and notes on the opposition are marked in blue. Since UN natal Uranus @17Gem02 Rx conjoins precisely the natal Uranus of Trump (17Gem53, his chaotic guiding planet), I'll say this chart shows Trump opposing UN leadership. Also conjunct @17Gemini is UN natal Nemesis (the unbeatable foe) and UN natal Psyche (or psycho?).
And the Prenatal Eclipse ('PE') of the UN is in the 1 North Saros Series ('The Mother of All Eclipses') in 4th house which repeated as The Great American Eclipse on August 21, 2017 @29Leo conjunct the natal Ascendant of Donald Trump and royal star Regulus (success if revenge is avoided). And since I've previously posted so often on these topics I'll not bore you with them tonight.
