The correct answer to this open question is the following.
What obligations, if any, do other countries have to accept refugees of any kind? Is there a special obligation if their lives are endangered?
No, not really. However, here we are talking about a humanitarian issue.
Of course, every country has its own laws and legislation about immigration. In the case of the United States, we know that this country was founded and formed by immigrants. Throughout US history we can see the many chapters, laws, and legislation created to control or limit European immigration, Asian immigration, and Hispanic immigration.
In recent years, and due to the strict regulations instilled by the Trump administration, a humanitarian crisis in the US-México border called the attention of the entire world.
These immigrants from Central AMerica -particularly from Honduras, El Salvador, and Nicaragua, were treated badly, as second-class people, and mass media and TV News covered the news a reported the harsh living conditions they were suffering.
It is truly a difficult situation that represents a major issue for both, the former country that does not offer the proper economic conditions to their citizens to prosper, and the right developed countries have to say no to receive a large number of immigrants.
It has always been a complicated debate.
