Once the president (played by Dermot Mulroney) realized he was attacked by Skrulls, he made every one of them enemies of the state and vowed to kill them all if they didn’t leave. This didn’t make Nick Fury happy, as he was hoping for a more civil response, but now humanity has begun to murder people in cold blood they believe are Skrulls.
And yes, if this sounds like a gripping, interesting story, you’re right. So of course it was introduced in the last 15 minutes of the series.
