I already own someone's home planet, and will soon have swallowed up the rest of his planets into the Earth Federation. I'm going to have to renegotiate terms with uranus. He's colonizing in my colonization zone, so I proposed either an alliance with me, or a stop to the colonization. Luckily I am in alliance with sirgumby, who is quite a large player. Not quite as large as uranus, but large enough to make any war too costly to fight without risking a third party coming in and taking some of Uranus' less well defended planets.
