Why is "1991 Yugoslav campaign in Croatia" trending?

Wikipedia Overview

The 1991 Yugoslav campaign in Croatia was an armed conflict between the Yugoslav People's Army (JNA), the Yugoslav Navy and the Yugoslav Air Force, and the Croatian National Guard (ZNG) then the Croatian Army (HV) during the Croatian War of Independence. The JNA was originally deployed in order to preserve Yugoslavia, and the initial plan of the campaign entailed the military occupation of Croatia and the removal of the Croatian leadership elected in 1990. The JNA intervention was the culmination of its involvement in the confiscation of weapons from Croatia's Territorial Defence, and in the Croatian Serb revolt that had begun in August 1990. From that time, the JNA had been frequently deployed to form a buffer zone between the Croatian Serb guerrillas and the ZNG or the Croatian police. In effect, these JNA buffer zones often secured the territorial gains of the insurgents and led to an increasingly hostile relationship between the JNA and Croatia. The JNA campaign plan was amended shortly before the campaign to include the relief of JNA barracks besieged by the ZNG. The besieging and subsequent capture of several JNA facilities allowed Croatia to arm its previously poorly equipped military and to equip and recruit new ethnic Croat conscripts and officers of the Yugoslav People's Army.
