Decorated war hero, father of the Queen, and he has no influence? I'm a Grey Warden, and I get to put a Grey Warden on the throne (or not). I also get to rule an Arling. And I'm no war hero, at least not yet. I may not even be human.
While he certainly seems resigned to his fate in his Awakening cameo, there's no guarantee at the time that he would be, and reasonable reason to believe he MAY have influence, or the opportunity to do more harm - see Sophia Dryden.
and PS - the one thing I've never accused him of is declaring war on Orlais. 
Nope, none. If you do make him a Warden, you conscript him, as a criminal, in front of the entire Landsmeet. What makes you think he can do anything? And yes,
you get to rule an Arling. Not Loghain, not Alistair, not Riordan. You do. What makes you think Loghain would get an arling?
What you can or can't do as a Warden is because you have the backing of Arl Eamon and the last remaining Theirin tagging along with you throughout Ferelden, not because you're a Warden. If Alistair wasn't Maric's son, then Eamon would do whatever he wanted on his own. He might use you, but you're still not much more than a pawn in his game.
He's resigned to his fate when you kill him, or did you not notice from him telling Anora that it was okay? What reason do you have that he'd change his mind? And Sophia Dryden is a very different case. She had a claim to the throne, lost it, got conscripted, the king turned out to be a jerk, the nobles wanted her back, and she started the rebellion. Loghain has no claim to the throne and no one wants him on the throne. He doesn't even want the throne.
