They were left to fend for themselves.      

If the children of lawbreakers are abandoned by their parents, it is the fault of the parents who are being held accountable for their lawbreaking behavior. How does it become "our" problem?

It is our problem in the same way that orphans become our problem.

Orphans of one nation are the responsibility of their own nation.
Lawbreaking behavior (breaking into and entering a nation illegally when legal processes are available) should not be rewarded.
The wards of the state are the responsibility of their own nation.
Do you somehow feel morally superior to those with whom you disagree?

I don’t agree here.  These illegals were working.  Children should never be separated by families.  Many of these people are Catholics and traditionalists should be outreaching to them before novus ordo corrupts them with modernism and sloth.  The fault lies with our greedy evil politicians and communist clergy and hierarchy who have encouraged these people to come to USA.  Why did that plant hire these people because they can’t find people to work.  Millennials don’t want to work.  And others are on drugs, drunk etc.  many people are able to work but many are on disability when they shouldn’t be including white people.
Many government agencies have been involved in child sex trafficking.   ICE needs to stop being cowards and go into sanctuary cities where the illegals are on welfare and are doing human trafficking and drugs.  It sounds to me they just wanted easy bust.  ICE should do their jobs and start going after these moslems who are here illegally or are traitors likely who are like the Muslim Congresswoman who married her brother...

What is happening at the border is an invasion and most of those people are coming in to vote and get paid. They aren’t asylum seekers.  And a lot of problems in South America is because of USA. Hollywood and politicians need their drugs laced parties with human traffic victims.  Some of Hollywood are buddies of these drug dealers.
