> he confirmed that he wants a database for Syrian refugees.

Doesn't the government already have database of all immigrants? I even have a nice card with a number, I'm pretty sure this number refers to a record in the database. Before I had that, I also had to fill in and send out certain forms, which I am pretty sure also went to some government database.

So how exactly Syrian refugees are different and what exactly makes the thing that US - and pretty much every other, as far as I know - government routinely does so beyond the pale?
