There are several reasons why Kissinger no longer appears to be the magician the world press had made him out to be, an illusion which he failed to discourage because, as he would admit himself, he has a tendency toward megalomania.

【翻译】基辛格似乎不再是世界媒体塑造的魔术师，其原因有几个。这是一种他无法阻止的假象，因为正如他自己承认的那样，他有一种妄自尊大的倾向。

illusion：假象；表面现象。它是the magician the world press had made him out to be 的同位语，而 the world press had made him out to be 是the magician 的定语。

用汉语表达就是：他是魔术师，是个假象。
