Simple:
1: I cliented Java on Turn Two.
2: You didn't.
3: It's MY SOI, so GET THE . . . FLIPPING BANANAS OUT!
If the rebellion wins, the rebellion wins. But it's my client state, not yours, and any attempt to blockade the area will be treated as an act of war upon Hawai'i, and a declaration of alliance with China. Thus, your fate will be the same.
Do not force me to fight you. Pull back and mind your own gosh-dang business. I don't waltz in and sponsor an unlawful rebellion or coup in New Zealand or Perth.
But I WILL if you try this.
Get out of my SOI or I'll sink your entire continent.
