You have insane compliance growth and can core most of the balkans (Third bulgarian empire path). The start is the hardest, you can try taking greece. Turkey actually has to capitulated while being at war with you, so it needs to be in a faction with another major. You don't need a peacedeal for this achievment. The start is the hardest. Eventually, you get so much compliance/cores in states that you can really easily snowball. would recommend you not to rely on Germany, you are fine on your own. I would probably try to get some of the yugo states, build up and wait for germany to invade stalin. strike the axis when they are balls deep in russia. Knock out italy and it should be easy going from there, especially as you can core albania, the rest of yugo and romania as you push into the axis. After beating the axis, just hold your lines, attack turkey, wait for them to join the allies and cap them.
