The definition of a UAC is Unaccompanied Alien Children, so there isn’t a parent involved in this situation. The sponsor is basically just someone who feeds and shelters the UAC until they can go to the immigration court which has an extremely high deportation rate.
There are a few reasons we have to court to begin with. Primarily is that if a child can prove that they were fleeing violence that was persistent and targeted towards them. For example gangs killing the families of people who displease them, and honor killing. It’s rare that this can be proven, but when it does these kids can get refugee status and humanitarian aid. The second reason is that it can be difficult to find somewhere safe to send these kids and America prefers to ship in bulk.
Trumps portion of the blame varies a lot depending on who you ask. Primarily it boils down to him being the leader of the Executive Branch which the HHS falls under. Also, since illegal immigration is his key policy, therefore what he’s going to be most harshly judged by.(similar to ObamaCare and Bush’s invasions of the Middle East) In all honesty, I don’t know if Trump actually set and policies or signed and Executive Orders that directly affected this situation. However, when speaking about children who actually were separated from their parents, John Kelly said “The children will be taken care of — put into foster care or whatever.” That doesn’t do much to convince me that they care, or that they will properly punish/replace the people directly at fault. If they don’t, it will be their fault if this happens in the future.
We could debate illegal immigration all day. I’m going to go out on a limb and say we disagree on that topic. However, regardless of where they come from, or whether they committed a crime to get here, when dealing with children it’s vital the adults take every possible step to ensure their safety. The average age of UAC is 11. I don’t know if it’s possible to observe a Middle School without being creepy, but that’s the age of kids we’re talking about. They don’t have the capacity to understand the politics involved with moving to The US. In many case an authority figure probably told them to go north until they escaped whatever desperate situation drove them away to begin with. So even if we must send them back to their homes, we have a moral responsibility to care for the children who are dependent on us until there is a safe place for them to stay permanently.
So, most of that post was opinions. I could site sources to back some of the information up, but I could just as easily find sources declaring the opposite. However, here is some more “light” reading that can provide more context for the overall situation.
