We call these attacks terrorism, elevating them over normal crime.
But what, exactly, represents an elevated response on our end? We simply pour more resources into finding accomplices and/or associates of the terrorist(s)? Is that extra investigative due diligence the extent of how we distinguish terrorism? When we give such acts of violence notoriety, and attention, it begs an expectation of greater action for response and prevention on our part.
"War on terror"... what war? I don't think bombing Pakistani weddings and others in the Middle East represents prevention. Sure, eliminating ISIS and their territory will help stem their organization and financing, but the ideology and identity of Islamic Terrorism will show up in vulnerable Muslim populations across the globe. Clearly western civilization's open and inclusive nature prevents separation and isolation from these violent offenders. We are incapable of keeping "them" out. Fact is they are here, and will remain, among us.
So a response it seems, besides investigative reaction, would be to address the Muslim community in ways that help assimilate and strengthen it against outside influence. That they do not associate or identify with Middle East groups bent on killing people. That way we isolate the spread of the "infectious disease" (the ideology) without violating who we are as a society. We can work on prevention without repeating the darker mistakes of human history.
But make no mistake... should America and Europe fail to act fully and adequately in dealing with this issue... such attacks will remain common and risk escalation. How many killed or maimed loved ones will our people suffer until we demand easy answers and bloodshed of our own? And I'm not talking on the other side of the globe, but on our streets. We must act for our people to help them find better, and more difficult, answers before hatred spreads too far.
