Suppose a bunch of crazy Americans went to some other country and caused several billion dollars in damage and killed several thousand of that country's citizens. America would be the FIRST to hunt those people down in order to exact justice.
These "terrorist" nations know that these evil people reside within their borders, and it seems that their attitude is "if you want them, you come and get them" — which makes that nation just as guilty as the terrorist. Yes, it's sad that innocent people must die, we already lost thousands in this one strike. We didn't have any warning. They do!
Maybe after their nation is no longer inhabitable, terrorists will think twice about dishing out something that they are not prepared to receive many times over in magnitude.
God bless us all!
