Ignoring the crisis wouldn't make it go away. Maybe it is possible to keep the refugees out, but that doesn't help them. The whole world has an obligation to help these people.
No one has an obligation to help any one else. You come into this world alone, and you will leave this world alone.
Yes, but if you help other people, then you might realize that you aren't that alone.
well if whole world has this obligation, I please our US friends to accept a mere million or two of these refugees. just for next 20 years. surely a drop in the ocean, especially since all this mess is directly caused by US war failures in neighboring Iraq, and refusing to wipe off ISIS to oblivion
