There is a widespread belief among Ukrainians that the Belarusian army will not go against Ukraine. And if such an order is given, it will turn against Lukashenko himself. Knowing and fearing this, Lukashenko delays entering the war. However, this opinion is based on a genuinely friendly relationship between the two nations, including the experience of the support that the Belarusians showed for the Ukrainians during the revolutions of 2004 and 2014, and on the general unwillingness to live under the leadership of the Kremlin. It’s notable that many Belarusians chose to flee to Ukraine seeking protection from Lukashenko's regime, as well as actively helping Ukrainian refugees during this war. However, the people and the army in Belarus are not united, as demonstrated by the rallies in 2020. There is little the Belarusians themselves can do if the army is ordered to attack. Still there is another factor traced back to history. Belarus was known for one very important element from World War II, which played a significant role in the German army's failure in the war against the USSR: widespread and well-trained underground resistance. Let's just say that the Belarusians may not be the most militant nation, but they are talented saboteurs. Since the beginning of the war, sabotage groups of Belarusians have mined the railroad tracks, preventing trains carrying ammunition from crossing to support the advancing Russian army. The people and the army in Belarus are not united. From sources that we cannot name, we know that individual Belarusian military, working incognito, are training Ukrainian soldiers at bases in Poland. Since early 2022, the Belarusian regiment named after Kastus Kalinovsky, the 19th-century Belarusian writer and revolutionary, has been fighting on the side of Ukraine. It took an active part in the defense of Kyiv during the first days of the war. Whether pockets of resistance turn into a mass movement is one more question we may find out in the coming weeks and months. Russians failed to muster the protest that would have stopped Putin's regime. Perhaps the fear of repression and the experience of clashing with the Special Forces will also prevent the Belarusians from significantly rebelling against the regime if Lukashenko decides to go to full-scale war. In this case, Ukraine will have to wage a defensive war on two fronts.
