The metaphors of cancer and terrorism are easily interchangeable. Breast cancer is a terrorist organization of cells, threatening mass casualties in the rest of my body. ISIS is a cancerous growth, metastasizing at an alarming rate. But waging war on cancer and ISIS do little to address root causes or prevent the conditions that cause these terrors in the first place.
Critics of the coalition may see military action as a threat and think that it will only intensify the problem. However, such critics seem to be ignoring that it was the inaction towards the atrocities in Syria and the failed state in Iraq that resulted in the swelling of ISIS's ranks from a few hundred to nearly 30,000 according to the latest estimates.
