would set a precedent for a political settlement in Kosovo—allowing Croatia to accept the plan with little possibility for it to be implemented. The RSK refused to receive, let alone accept, the plan. In December 1994, Croatia and the RSK made an economic agreement to restore road and rail links, water and gas supplies, and use of a part of the Adria oil pipeline. Even though some of the agreement was never implemented, a section of the Zagreb–Belgrade motorway passing through RSK territory near Okučani and the pipeline were both opened. Following a deadly incident that occurred in late April 1995 on the recently opened motorway, Croatia reclaimed all of the RSK's territory in western Slavonia during Operation Flash, taking full control of the territory by 4 May, three days after the battle began. In response, the ARSK attacked Zagreb using M-87 Orkan missiles with cluster munitions. Subsequently, Milošević sent a senior Yugoslav Army officer to command the ARSK, along with arms, field officers and thousands of Serbs born in the RSK area who had been forcibly conscripted by the ARSK. On 17 July, the ARSK and the VRS started a fresh effort to capture Bihać by expanding on gains made during Operation Spider. The move provided the HV with a chance to extend their territorial gains from Operation Winter '94 by advancing from the Livno valley. On 22 July, Tuđman and Bosnian President Alija Izetbegović signed the Split Agreement for mutual defence, permitting the large-scale deployment of the HV in Bosnia and Herzegovina. The HV and HVO responded quickly through Operation Summer '95 (), capturing Bosansko Grahovo and Glamoč on 28–29 July. The attack drew some ARSK units away from Bihać, but not as many as expected. However, it put the HV in an excellent position, as it isolated Knin from the Republika Srpska, as well as Yugoslavia. In late July and early August, there were two more attempts at resurrecting the Z-4 Plan and the 1994 economic agreement. Talks proposed on 28 July were ignored by the RSK, and last-ditch talks were held in Geneva on 3 August. These quickly broke down as Croatia and the RSK rejected a compromise proposed by Thorvald Stoltenberg, a Special Representative of the UN Secretary-General, essentially calling for further negotiations at a later date. In addition, the RSK dismissed a set of Croatian demands, including to disarm, and failed to endorse the
