Regardless, the people would see the Gaians as lunatics that were bombing things to achieve something the government is already trying (New London used to be almost as bad as Leeds on the Planet, for instance). And I doubt they care about the evils of terraforming, seeing as Harris and Ayr were uninhabited by any lifeforms beforehand (OMG, they're bringing life to a rock! I'm going to give money to terrorists! Whoo!).
