Answer:
Yes (Short term) and no (Long Term)
Step-by-step explanation:
The war on terror can be divided among different terrorist organizations. You can successfully bring down a terrorist organization but that does not mean it will rise again or another one would start. Example: Al-Queda was taken down but now the UN and Middle Eastern countries face ISIS. If the message of Radical-Islamic movements is still present there will be terrorism in the middle-east. Or if Ireland is still being suppressed by Britain the IRA will still stand. Extreme-Anarchists as well in France, Spain, Britain, etc will still use violence to prove a message. The Ku Klux Klan will still use violence and fear to get their way as they advocate white supremacy. All of these terrorists organizations could be brought down but that doesn't promise that they would ever rise again or start another movement.
