Here's my answer.  Jesus didn't care about sovereignty of nations.  He would expect his followers to help anyone who showed up in their country in need.  He didn't care about nations, borders, or pragmatic considerations.  The Church may teach otherwise, as it is very concerned about pragmatic considerations and sovereignty, and not so much with what Jesus had to say.  What's amusing is your handle is "faithful catholic" but your rhetoric indicates you are more a nationalist that a catholic, and your faith is most likely tempered by what you consider to be best for you and yours.
