On 28 February, Ukrainian President Volodymyr Zelenskyy called for NATO to establish a no-fly zone over Ukraine, saying that "if the West does this, Ukraine will defeat the aggressor with much less blood."[3] Later that day, American White House Press Secretary Jen Psaki stated that American troops would not establish a no-fly zone over Ukraine, stating that "it would essentially mean the US military would be shooting down planes, Russian planes," which she described as "definitely escalatory, that would potentially put us in a place where we are in a military conflict with Russia."[4]
