Uneasily, yes, they are :) Roosan, that is a choice you actually have- the previous Lord Tully was isolationist, and likely declined an offer from the Westermen to marry off Tywin to one of his daughters. As his heir, you might think different...or hear the rumours that King Aerys Targaryen is on the throne, and just beat back the Crakehalls...with the Reach barely playing it's hand :D So yeah, you're still an important figment in all of it, and who knows what you could do.
