If only I could use my only country against you manmohan, because I don't think i'll be that much stronger than you in terms of military strength, which would make the war fairer. Also i'm on LU too.
The problem is though, is that I don't want to lose control of my only country if I ever lost a war, of which you don't either.
So the way to solve this, I think, is that the GMs should make another important option for your main, just like the "Secured mode feature", is to have a "Remain in control of your country after defeat" feature, for when you lose a war.
I feel with this little feature, we would see petty single countries warring against each other, especially if those between war levels 0-2 could battle each other within those levels.
