Ukrainian pilots plead for F-16s to counter Russia's air force.

Ukrainian pilots have implored the West to supply them with F-16 fighter jets, as they describe the difficulties of fighting against Russia's dominant air power. The pilots say that the counteroffensive would be "more effective and much safer" with F-16s, as the country's aged Soviet-era Su-25s can't compete with Russia's Su-35s, their radars, and long-range missiles. Some pilots believe the US-made F-16 fighter jets would be a "game changer." However, a Pentagon spokesman recently said sending F-16s to Ukraine is a "long-term" endeavor and "will not be relevant to the upcoming counteroffensive."
