European perceptions on who should defend Ukraine if invaded by Russia in 2022
According to a survey conducted in 2022, 62 percent of people across seven European countries thought that NATO should defend Ukraine if it were invaded by Russia. Although Ukraine is not a member of NATO, further eastward expansion of the military alliance has been described by Russia as a "red line", and is one of the main sources of tension in the Russia-Ukraine crisis of 2021 and 2022.
