Should countries open their borders to migrants?

Should countries open their borders to migrants? 

I think that they should open their borders to migrants. Because if they stay where they are, they can get hurt, killed, or forced to do things that they don't agree with. Germany won't let them stay there, so they have no where to go. They can't go back to where they were because their lives are in jeopardy. 

I think that Germany should set up a place for them to go. Kind of like back when the United States was in the cold war, we put the Asian-Americans in camps where they could live their lives and go to work. I think that Germany should do something like that for the people. 

I don't agree with what Germany is doing to these poor helpless people. I was raised to believe that if someone needs help, you give them all you can.
