Awwww is the widdle general wee gonna take his ball and go home?
There is something truly despicable about the mindset that says "if I don't get my way with player A, I'll throw the solo to B, and I'll use the threat of that as a diplomatic tool". I just can't have someone throw that kind of childish threat at me and respect their style of play. If I decide early on to attack one country while allying with another (which is essentially the starting point of every game) and the country I decide to attack, rather than trying to turn my ally against me or recruit others to his cause, plays the "I'll take my ball and go home" card, thinking that I'd rather do what he says than get a survive at the expense of someone else's solo, then my new goal becomes defeating the childish bastard. A win, draw, survive or defeat only lasts the duration of the game, but integrity and honor exist outside of the game.
If you can't turn people through diplomatic means, than it just wasn't your game. Fight to the death and try to screw your enemies if you can, but to just give up and throw your shit to someone else for a solo because you don't get your way is a lame ass pussy move.
