Oh yes! What a great thread idea is this
1) SRK!! I take control of North Korea forming the Socialist Republic of Kokorea (or Co-Korea). I correct all the wrong Kim Jung-Un has done and fix all relations of countries with former North Korea. I negotiate the reunification of the Koreas, forming the United Socialist Kokoreas, or better known as Kokorea
2) With such good relations, I have a strong influence on foreign affairs (like, countries come to me for help). So, Spain and Catalonia end up coming to me and I declare Catalonia be an independent country.
3) I argue in favour of the formal recognition of Taiwan as an autonomous country, and this encourages others to recognize Taiwan as an independent nation. The yay's outnumber the nay's and yay! Taiwan is officially independent.
There's no reason for these; just because.
