2.) Why was SHIELD's 'overlords' so bent on nuking New York City? The state government of New York was already sending in National Guard units to fight the intruders, and, eventually, the United States government would commit forces to the battle. (This would imply the battle had been raging for an hour, at least.) The 'overlords' reaction seemed odd to me, especially when it was clear that the intruders were contained to a 3-block radius around the portal. It becomes even more interesting when it is revealed at the end that a nuke could destroy the command center, and that the portal could be shut down by a specter being jammed into the portal generator.
