Daria Kaleniuk, founder of the Ukrainian Anti-Corruption Action Center, confronted British Prime Minister Boris Johnson at a press conference in Warsaw, saying that "Ukrainian people are desperately asking for the West to protect our sky... You are saying in response it will trigger World War Three, but what is the alternative? To observe how our children – instead of planes – are protecting NATO from the missiles and bombs?"[9] Former Ukrainian Minister of Defence Anatoliy Hrytsenko argued that a no-fly zone was needed to "stop Russia from launching devastating missile strikes, dropping bombs or undertaking large-scale air-assault operations using helicopters and aeroplanes."[10]
