How to handle asylum seekers?

I recently learned that it is illegal to send asylum seekers back to their home countries.

It is also very cruel.  These people have been victimised in their homeland.  They are fleeing some kind of terror that they have faced over there.  To turn them back to the horror that they are trying to escape from ... imagine yourself in their shoes and you would understand how unkind it is to do that.

However, some asylum seekers are not really running away from anything.  They are just looking for better economic prospects.  They are illegal immigrants.  Some may also be terrorists seeking a way into the host countries that they will later terrorise.

And some potential host nations also lack the resources to take in these people.  Nobody has the right to demand that any host country take them in.  Asylum seekers should wait for host countries to accept them - not demanding or expecting to be welcomed any more than the people who apply for migration.

So what can we do with asylum seekers?  Send them to detention centers and process them?  That seems to be the way most are handled.  But this method should also be temporary - nobody should have to stay in detention centers and be in the processing stages for the rest of their lives.  Otherwise, detention centers are just a guise for lifetime imprisonment.

How should we handle asylum seekers?  How can we give them refuge and care?  Who are genuine and who are not?  What do you think the world should handle this problem?
