This is not to say everything is hunky-dory. But it is to say that this is no longer World War II.
edit: Where do you think all the Syrian and Lebanese restaurants in America came from? Refugees from the collapse of the Ottoman empire post-WWI. It was just as bad then as it is now. But it can get better, and I am totally convinced it will.
Every wave of immigration that made America what it is today came from people fleeing poverty and violence. Hardly anyone emigrates away from a safe, comfortable life with family and friends and familiar sights nearby. In the 19th century, 20% of the population of Sweden came to the US to escape famine. Sweden was 90% illiterate, mired in extreme poverty, with a birth rate above 5. Now, it's... Sweden. The most civilized country in the world.
If Sweden can evolve from an impoverished hellhole to being the epitome of modern civilization in a century, why can't the same thing happen to Syria? Or Sudan? Or Myanmar? I think it can, and it will.
