How do I implement islands into my simple Polygon2D/Line2D based graphics map game?

I am making a “game”(rather a world war bot 2020 clone ) in Godot. I’m only currently working on the map graphics.
One thing I have a problem with is islands. I could attempt to do them with additional polygons, but that would work only for territories, not country borders. Those work based on merging the polygons of the border territories of the country, and wouldn’t work with islands.
My only idea is to instance more Line2Ds, but that is most likely not a very good solution. Unless I should change how the Line2D works for the individual territories to allow for islands?
