The Second Yugoslavic War (Or War to Reunify Yugoslavia or Osvajanje in Propaganda) is the name of a conflict that took place in Southeastern Europe from 2030-2032. The Cause was the depression that afflicited Europe and an unexpected grab of power by Serbia's Socialist Party.
In 2030, the Socialist Party of Serbia seized power in hopes of reunifiying Yugoslavia. The Party began by declaring its intention to exploit a weakened Europe, plagued by Depression and the Growing threat of War between Russia and the United States. President Marco Rubio in the U.S., was unable to respond to the crisis and was forced to remain neutral. This allowed the chips to fall.
Serbian Unification Campaign
On December 14, 2030, Serbia began an incursion into Croatia. The Puppet Government installed there proclaimed itself the succesor to the Socialist Republic of Croatia, and intended to join the Serbian Campaign. Despite the victory of the Serbian-Backed Army, the War dragged on, leading to an impossible stalemate. In Macedonia, Slovenia, Kosovo, and Montenegro, the Serbians backed a series of military coups by Socialist Supporters, with each formally declaring the establishment of of their Socialist Republics, with whatever resistance unifiying to fend off Serbia
On March 18, 2031, the Republika Sprska, declared its independence from Bosnia. The Civil War, which had already been a challenge for the Serbians in other countries, became an even deadlier one in Bosnia. The President of Bosnia pleaded with NATO allies for support, accusing the Serbian Army of invading the Country. The Resistance that fought the governments of each country, however, were natives to each nation. Unlike another major european war, This one was well crafted, and the Serbians had the upper hand.
Croatia had fought the Serbians individually, not asking for NATO assistance. They knew the seriousness of the economic crisis, and did not want to risk completely bankrupting the West.
