I assume the Polish attack on Russian or Belarusian forces would come in reaction to a Russian or Belarusian attack, in which case NATO should already have come to the aid of Poland. Things can get muddled in the light of the alternative ways of "waging war" which Belarus seems to be engaged in - e.g. inviting thousands of migrants with promises of an easy passage into the EU, providing them with simple armaments [1] and positioning them on the Polish border with no way of retreat back in to Belarus - which has led to both NATO as well as Russian forces to converge on the scene [2], a situation in which the question of "who fired the first shot" is hard to answer.
