Maybe, maybe not. Spain went through this for decades with ETA and they eventually stopped, we went through it with the IRA and they eventually stopped, Al Qaida have been pretty dead since ISIS became the cool new brand for radicalised muslims. I don't see it ending any time soon, but history shows these terrorist groups don't usually last forever. Some other cunts usually turn up thoughSo sad. Have they caught all suspects?
Sadly I don't think we will ever stop this. Will be just part of our everyday life from now on and will undoubtably get worse.
