"The devil made me do it"
You know, before reading more of your discussions, I thought you only had a problem with the Spectre and tried to demean him at any occasion you get. Only now I realize that you actually just flat-out mis-interpret information in order to make it seem as your opinion on a certain events/characters is correct, and thus make characters you don't like look weaker than they actually are.
I'll handle the Sinestro Corps War point first. The galaxy-destroying blast was contained within the perimeter the Green Lanterns set. It's obvious that what that Green Lantern was talking about in the scan you posted was the stopping of the anti-matter wall, which Anti-Monitor used to start feeding on the positive-matter.
How did Henshaw get away from Earth, and how his remains weren't on Earth after the battle was done ? It was actually shown, that whenSuperboy Prime bfr-ed Anti-Monitor, Henshaw's remains were right besides Anti-Monitor's.
I hope you can admit when you are wrong, and are not the type to grasp at straws and such. 🙂

Now, unto the 'exploding planet' point. It was made pretty clear that the entire planet was rebuilt using the Green Lanterns and power rings and that they were siphoning power from OA. As you can see in the scan, that power was collected in a power battery sort to speak, from which the lanterns Hal fought as Parallax were tied to. (The Manhunters even asked Henshaw if they should take Hal aswell so that he too will provide acces to the Central Power Battery too)
Now, what you missed in the scan is that controlling the Highmaster, Hal and Arisia shot the the collecting power-battery that I mentioned earlier and not the planet, battery which flat-out exploded with Henshaw a few feet away from it and considering how much power that battery had, it is much more impressive than an exploding planet, which occured after this event.
Again, I hope you can admit when you are wrong 🙂
