No it absolutely positively was not in any way shape or form related to War of the Worlds. Not the book, not the original movie, or that crapfest of a remake. No. You have completely missed the SINGLE point that War of the Worlds was trying to make if you think that. War of the Worlds is about man's arrogance and despite their technological advances they are unable to over come an invading alien race, however are "saved" by a tiny micro-organism. ID4 is about man's success in using their own technology to over come an invading alien race. See the difference ? HGWells was making a point, while Will Smith et al were making an action movie.
