Casper Weinberger, the defense secretary, was born on Aug. 18, 1917, and has his Sun in Leo. This Sun, with its powerful planetary configurations (especially with Uranus) endows him with a strong ego, a penchant for dramatics (he probably loves the theater) and more than a touch of rebellious stubbornness. And yet, this powerful Sun, because of its position on the chart, is not a dominant force in his life. In fact, Weinberger may be self-effacing, which is quite unusual for a Leo, but, as I said, the ego (Sun) and its needs do not drive his life.

A planet that is to the forefront, and provides the impetus and the motivating force, is Mercury, the planet of the mind, making the workings of the mind the most important thing to him. He is proud of his mind and he would like to be appreciated and praised for it.

And his mind is excellent. It is well balanced between originality and practicality, attentive to details and capable of perceiving an entire picture.

A person with such a Mercury configuration takes more pride in the way he arrives at conclusions than in the conclusions themselves. He is the kind of person who likes setting up a hypothesis to build a case (an excellent legal mind). Anyone wishing to make Weinberger change his views would have to begin from the inital premise and find a flaw in the logical flow of his thinking, and such a flaw may be rare.

Weinberger has been strongly pushing for our military buildup, and yet his chart clearly shows that his views do not spring from any desire for aggression. In fact, quite the opposite is true: Since some of his planets are strongly connected with the planets of the USA chart, Weinberger feels protective of this country and unwilling to expose it to even the smallest of dangers. Because of that sense of protectiveness and preservation, he will be loath to expose even a single military man to unnecessary danger. This attitude (which is rather nice to find in any secreatry of defense) will make him quite negative toward any situation, or any country, that he feels is endangering the safety of the United States, be it in the military, poltical or diplomatic arena.

And yet it would be a terrible mistake for anyone to equate Weinberger's feelings of protectiveness, caution, a certain degree of reticence and a nonagressiveness for the actions of a fearful, overly cautious man. If any "hunting party" comes to close to this lion guarding his cub, watch out, for it will face a ferocious, roaring, man-eating lion.

There were press reports that Weinberger and Alexander Haig did not get along very well and that their feud caused internal problems for this administration. It might be interesting to compare the charts of Weinberger, Judge Clark and the new secretary of state, George Shultz.

One thing that immediately leaps from the three charts is that they will present similar views to President Reagan, but those views will be arrived at and presented in three totally different manners, since the three are quite different in their makeup.

But where they mesh, the result is constructive and harmonious and even their differences will be handled productively. The charts of Weinberger, Shultz and Clark indicate these men are not driven by their egos (in contrast to Haig, whose chart was driven both by his ego and his intellect). All three men put their highest value on sound, orderly thinking, on logic, on an ability to see the entire picture.

And yet while their reasoning processes are similar, they use the additional strengths of their particular charts to arrive at their conclusions. Clark adds his intuitive ability and a deep psychological perception of people. He literally smells the problem and the people, but he will never pass a judgment on his sensing alone. He uses his intuition and his sixth sense to investigate the area of brewing danger.

Shultz will always try to balance his quick, original and daring perception of a problem by the reality of what can and cannot be done, by the economic laws of balancing demand with the supply.

And Weinberger will immediately think of statistics, of the cost per unit, and whether the decision may make one of our flanks vulnerable somewhere.

This will be a very fruitful and harmonious group, for even if their conclusion might not always be identical, their thinking processes are almost identical.

Currently Weinberger's chart shows aspects indicating changes (which occurred with the departure of Haig). Moreover, the eclipse of July 6 also fell on his chart, which probably indicates the war-like conditions and the possibility of a religious war with the Iran-Iraq conflict, following on the heels of the Lebanon crisis.
