If North Korea invaded... America? HAHAHAHAHAHAHAHA! The United States being invaded by anyone is as fictional as super heroes. You don't nuke Seattle, you nuke North Korea, that's the difference between an invasion by a country and an alien force. I expect the Security Council would have shoved the nuke up the Chitauri's ass if they had thought it were possible. Iron Man made it possible.
No, the nuke would not be the first response, the Avengers would
. The military would not add to the tension, they would steal it. What added to the climax was one of our heroes "laying down on the wire" and sacrificing himself to intercept and guide the nuke through the wormhole to destroy the mothership and end the Chitauri threat. How does the military make that ending better?
it adds to the tension because the military can't do anything against the invasion. It adds to the tension because now only the Avengers can fight the enemy.
Steal tension??? No one can steal tension. Tension is either added to a scene or taken away.
Screenwriting 101: anything that adds to the tension of a scene is a good thing. Let's look at one of the best endings of a movie Star Wars: A new hope. We have the tension of the death star bearing down on the moon of Yavin, We have most of the X-wing pilots getting wiped out by and the last resort in rookie Luke Skywalker. The tension is ramped up when everyone tries to blow up the Death Star and fails...
...now imagine in Avengers the military shows up and is stomped by the Chitauri. Tanks blown up, jets destroyed...a squad of soldiers cornered...Chitauri bear down on them....Cap saves the day and then they go into the whole Avengers assemble scene. Tension is ramped up and now when they council decides to use a nuke it makes sense because they used all their ideas.
