preeminent

Bombastic boasts—"We are positioned to become the preeminent provider of XYZ"—do not constitute a position.

言过其实的自夸——“我们定位于成为XYZ的卓越供应商”——并不能构建其地位。

And there is every reason to think America will once again regain its preeminent role as an American powerhouse.

我们也完全有理由相信，美国将再次赢得美利坚强国的卓越地位。
