A ceasefire is generally more limited than a broader ceasefire, which is a formal agreement to end the fighting. Ceasefires can be misused by the parties for rearmament or re-establishment of troops and they generally fail when they are referred to as “failed ceasefires”;  However, successful ceasefires can be followed by armistice and then peace agreements. The ceasefire of 27 July was a step forward and, without a doubt, an important step towards the end of the Donbass conflict. However, previous ceasefires have been eroded quickly and without obvious reasons or warning signs. This ceasefire could not ultimately be different, as fighting continues along the front line. The war in the Donbass remains the Kremlin`s main lever of influence over Kiev. In the future, the Kremlin may look for ways to flex its muscles in Eastern Europe as a sign of strength amid internal political protests and signal its geopolitical power to the West as a new government takes power in the United States. This could lead to an upsurge in hostilities in the Donbass in the coming months. As of 10 November 2020, Russian troops and armaments, which were to be a peacekeeping force under the agreement, are expected to enter the Nagorno-Karabakh region.  The force was reportedly airlifted to Armenia prior to the signing of the agreement.  On 12 November, the Russian force consisted mainly of personnel from the 15th Motor Rifle Brigade, which had entered Stepanakert and began deploying observation posts throughout the region.
 Andrusovo Ceasefire, in Polish Andrussov (January 30, February 9, 1667), a long-standing treaty that ended the 13-year war (1654-67) between Russia and Poland for control of Ukraine. In 1654, the Russian government accepted the Perejaslav agreement, a proposal for annexation of Ukraine by the Hetman (military leader) of the Saury Cossacks, Bohdan Chmelnytsky, who had led a revolt in Ukraine against Polish rule (1648-54). This agreement sparked a war between Poland and Russia. During the war, control of Ukraine shifted many times, and the allegiances of the inhabitants were sharply divided, some preferring Russian domination, others Poland. Peace negotiations began in 1664. Although Polish military achievements and Russian exhaustion gave Poland a negotiating advantage, the outbreak of a new rebellion forced the Poles to accept conditions favourable to Russia. Under the ceasefire, Ukraine was divided along the Dnieper River; Russia received the eastern part of Ukraine, the city of Kiev and the provinces of Smolensk and Seversk. The ceasefire was confirmed by a treaty of 1686. On 3 March 1991, Iraq and the United Nations Security Council signed a ceasefire agreement after Iraq was driven out of Kuwait by US-led coalition forces during Operation Desert Storm.
