I was thinking we could tell them there is a Marxist, gun-free Nirvana up there and we could stay home. We would tell them it even has perfectly breathable oxygen and is nice and warm - no need for protective gear, just open the door and jump out...If it's a planet populated by fuds and moonbats, then just nuke it from orbit and be done with it. Their defensive grid will be a joke, and not be able to hit 'minute of starship' at any range. So, if the planet has resources you want, remove the infestation and then land. If not, just crack that sucker open and move on.
