Invasions is an anthology of science fiction short stories edited by Isaac Asimov, Martin H. Greenberg and Charles G. Waugh as the tenth and last volume in their Isaac Asimov's Wonderful Worlds of Science Fiction series.

The book collects fifteen novellas, novelettes and short stories by various science fiction authors, together with an introduction by Asimov.
Usage examples of "invasions".
Who knows why Saddam might want to do such a thing--to gain a better position to influence the Arab-Israeli dispute, to reassert his bid to Arab leadership, or for some other reason known only to himself--but his invasions of Kuwait and Iran were equally mystifying at the time.
From then on, military invasions would again be the monopoly of the generals.
