I'm not sure the Xiliens can even get to within a Lagrange point on Earth's orbit given the force you assembled here.

Forget the Yamato (both the ship and Gundam Jesus) -- the three Macross ships, by themselves, are enough to repel everybody from Planet X, no matter what version you go with. Same with the Nadesico, despite being a smaller ship. The Ptolemaios has both invisibility and teleportation, so the Xiliens will never see Celestial Being until it's too late. And the mobile suit complements for the Gundam ships range from "can push back a giant space station" to "humanoid Death Stars with invulnerability and portals" to "body-blocks a superlaser and heal from it through time travel" so it's gonna be hell for Xiliens to not even punch through.

You can keep the Wunder on Earth to intercept any kaiju sent out, but would they even matter? Gigan is fast, sure, but easy to intercept and kill for the Gundams -- really only Monster X/Keizer is the threat to worry about, as some attrition will be expected in trying to kill him. But you have Macross ships. You have Yamato.

And bet your sweet ass that Douglas Gordon's gonna be chuckling and hollering at the sheer power surrounding him. He's enjoying the spectacle as Captains Okita, Jenius, Bright, Murrue, Sumeragi and Commander Ruri Hoshino show the power of humanity. No Godzilla, you say? No problem. No problem at all.

10/10 they never lose this war. Front-loading this many military assets onto one enemy is overkill.
