My analysis:
It has the same resolution as the following situation in standard
diplomacy (all moves legal, no cut supports):
A moves to B with one support
B moves to A with two supports
D moves to A with two supports
Country 1:
A - B
C S A - B
D - A
E S D - A
F S D - A
Country 2:
B - A
G S B - A
H S B - A
I believe nothing moves
