I dunno why I hadn't thought of this earlier:

If you recall the subtext of the Alien film series, the Corporation wanted to bring Aliens to utilize as killer-soldiers eventually so they set out to capture/breed the organism for their nefarious uses. This wAs particularly well delineated in the second installment.

In the same way, Trump has used ISIS as the Middle East weapon against anyone he wishes: they can’t be reasoned with or negotiated with, they only kill and destroy whole cultures. On the one hand they were defeated utterly (yeah right) but on the other hand they are always present and ready to strike at the heart of a country.

The only problem is that you can’t send them out the airlock into the vacuum of space. I’m talking about the Trump family, not the Aliens.
