Like most internet meme phrases, this is both trite and inaccurate. The cruelty is not the point. This administration has decided foreigners are the scapegoat, and wants to get rid of as many as they can. It’s heartless, but cruelty is not the objective.
The ultimate goal might be some political aim and in that sense cruelty is not the ultimate point but what is usually meant by this phrase is that the cruelty is not an unintentional oversight, an unintentional side effect. It is intentional (and there to achieve the ultimate political goal).
Normally I’d agree. For this admin the cruelty does actually look intentional as a deterrent. Making it intentionally turbulent to discourage people from trying in the first place.
Cruelty is what their base voted for. This is fan service.
Yes cruelty is the point for this admin and its voters. They think it makes them more manly looking. They openly brag about it. They glee in it. They go out of their way to endanger goals just to be cruel.
All of that is in the open, if you listen to what they say and watch what they do.
Using people as a scapegoat so you can parade their suffering for your fans is intentional cruelty.
