It's not about stealing time from the heroes. Showing the military being ineffectual against the aliens would have done two things: 1) it would have added to the tension of the climax. Conventional forces are useless, who can we turn to? The Avengers purpose in the world is now clearer. 2) it makes sense. Going straight to the nuclear option is not the proper procedure. While there isn't a standing procedure for alien invasions there is one for invasion from a hostile nation. Imagine if North Korea invaded Seattle...would our first option be nuking the city????
