Yes.
There are two ways to go. We do little except try and catch specific individuals involved and make the US a police state to stop future acts.
Or we completely re-organize our national defense, security and international relations.
We can bring it out to those who are part of this enemy axis and stop it. That means US military presence and action in the world.
Or we can become a police state ourselves.

Well, consider this: When I was growning up, you could get on a plane as a passenger without having luggage or your personal things checked ... But today, would you even get on a plane that did not check? We DO give up some freedoms for security.
The achille's heel of your argument is your paraphrase -- what you selectively left out. The full quote is: "Those who would give up essential liberty to purchase a little temporary safety deserves neither liberty nor safety."
The key phrase here is "ESSENTIAL liberty." What part of Cohen's description are you considering "essential liberty"?
