Is most important the life of european that a syrian person?

During the last weeks in the TV I can what the terrorist attempts in Paris. I can understand that in Paris the attack it was unexpected. But I think that in Syria all the time there are attack. Most of the people are surprised and alarm for the terrorist attempts in Paris. The European Union and all the other countries help and sponsor France. But why opposite others terrorist attempts in Syria the world didn’t react with this sponsor. Because the world didn’t react the same way? In my opinion before the terrorist attempts the government should have taken securities measures and prevent this acts.
