I only decided to gamble it off by joining the Allies when the Brits forced Italy to capitulate, thus connecting our borders. I want to praise the British and the Commonwealth though, because they've launched a very successful amphibious assault on Italy. That's pretty much how I got in this situation. SU declared war on Poland, so they're at war with he allies, but I've refused to join this war, because I'm not ready to face the Soviet horde. The Allies only got involved after Germany demanded Danzig, Poland joined the Allies, and them Germany put pressure on the Benelux through their NF, then France and Benelux also joined the Allies. It was a quick war, which I was laughing inside because the Czech refused my offer of guarantee from the NF. The war started when Germany demanded Sudetenland from Czechoslovakia that have joined Romania's faction.
But the war is still going on, I just hope I can keep the lands where I have claims on. I joined the Allies to combat Germany (which have annexed Czechoslovakia and Romania) and Yugoslavia that have joined Axis.
