Yes they are, because they live under the kind of rule you advocate for, one of tyranny.
Oh, you say, Venezuela (among others) does not want the migrants back? And, really, they are good people? Then conduct a vote among them as to whether or not Venezuela (or any other country) should be invaded and their ruling gang of thugs killed or jailed. Then if the vote is yes, do just that and install the migrants into power. If not, then find a suitable place outside the US to resettle the migrants.
My surmise is that such a threat will need to be carried out only once.
