You just love to bend the knee that easily? Why?
Otherwise all the other countries will also get SI, just slightly later, in which case there is not really that much benefit to being the "winner" who got there first.
With this in mind, I don't want anyone to "win" at SI and anyone who does is probably a sociopath or worse.
But then this would be considered an act of war, so then the killing starts.
Not saying I think countries should be trying to win, but I don't think this win condition is impossible.
