Three nations? Why waste the time and effort of three nations for something that could easily be done with one?
Does it really need to be brought up that you sold infra to get to that point, so you had more soldiers than a 10k nation? Apparently it does, I'm not so sure why you think this is such an incredible feat.
That being said, you like war, we like war, so let's have some fun. You claim that you're indestructible, and that may be so, but there's nothing you can do that a simple $3mil from our bank won't fix.
