I think that YOU do not understand that Isis is politically motivated but what happened in Roseburg was (probably) not.
Think chess
Why not please explain to dumb old me how what happen in Roseburg has anything to do with international politics.
I don't know how I can explain it any simpler, but I will try. Maybe one point at a time will be easier for you to comprehend.
1. Terrorist want to commit terrorist attacks, that is why they are called terrorist.
2. Terrorist want the world to know what they did
3. Media will cover any mass shootings anywhere anytime, large town, small town ....someone commits a mass shooting the media will come...hence reference to Roseburg
4. Terrorist attacks anywhere (well almost anywhere) will be covered by the media
5. Terrorist not dumb
6. Terrorist attack in large metropolitan city showing they can and will
7. Media will come to cover the story
8. Terrorist attack large town showing they can attack large town
9. Media will come to cover the story
10. Terrorist attack small town showing that the can attack anywhere they want
11. Media will come to cover the story
12 Metropolitan, large, or small...shows people you are not safe anywhere if the terrorist decide to attack. Terrorist makes their point
Reinforcement time
The media will go anywhere there is a story. Incident in Roseburg media present, incident in Boston media present incident in Paris media preset
Terrorist wants the world to know they will attack anywhere and they know the media will cover the story
