This.
Also, remember Reagan got elected a few years earlier partly because Carter COMPLETLY screwed up the Iran Hostage Crisis, and leaving many Americans feeling angry and humiliated.
One of the main "sales pitches" for teh ncessity of invasion was the possible threat to several hundred American college students that had been going to a cheap-o medical school on Grenada, and the possibility that they too would be taken hostage.
In reality, they hadn't been allowed to leave, but the Grenadians really hadn't bothered them much, and they were recovered unharmed. They WERE quite happy to be rescued, though, since it COULD have gone bad, and seeing smiling American students liberated by heavily-armed US troops went a long way toward justifying the invasion for many Americans, outside the geopolitical/anti-communist thing.
That aspect was also woven into the Heartbreak Ridge movie.
