Underlying difference?

Terrorism is the new normal

Let's declare war on ISIS

Now granted, Hillary Clinton is not going to get up in front of Americans and tell them that they must live with terrorism. But there are plenty of people on the left who believe as much and there are plenty of arguments being made that radical Islamic terrorism cannot be eliminated, rather only contained.  Moreover, by arguing (as liberals have for so long) that terrorism is a police (not a military) matter, you are by nature being somewhat reactive vs proactive. When you accept it as a criminal act, like any other murder or disruption, it emboldens it into our society.

Now I am not arguing that the concept is wrong. It may be long past the time where we can still hope to stamp out Islamic Terrorism at the root, and watch the entire movement crumble. But that doesn't mean that the American people (or Western society as a whole) is willing to concede as much.  They still want leaders who are willing to try to defeat (not just contain) radical Jihadism.

At the very least, they want leaders who are willing to face ISIS and radical Islamic Jihadism head on, and turn it into a good old fashioned fist fight. I think many people are tired of sitting back, while the world's leaders allow western society to be little more than a punching bag for Islamic terror... with their only reaction being a call for calm and a show of pity for the victims every time the enemy is allowed another free shot.

Instinctively, at the core, Americans want more than a moment of silence or a call for unity. They want to see us fight back. They want to see justice for those who are killed in these acts of terror. They want our leaders to be proactive in protecting our citizens. They want to see leaders putting safety ahead of politics. What they don't want, is more lectures and excuses.
