The attacks in Turkey, Brussels and Paris were coordinated and led by ISIS. In contrast, the attacks in Orlando or San Bernardino for example, were coordinated by lone wolf American citizens aspiring to attract the attention of ISIS. This distinction is important because each form of terrorism calls for different responses.
It's generally not war that refugees choose to remember, but the people who help you. My mother's colleague who snuck us out of Serbia, French volunteers who took refugee kids camping, and those who came to welcome us at the airport when we were resettled in Ohio; those are the people I think of daily. I hope Basel finds such people on his path too.
