The two full-scale wars that began a year apart - the Russian-Ukrainian and Arab-Israeli wars - clearly demonstrated the critical importance of combat aviation. The lack of dominance or at least parity in the air was the main reason for the failure of the great Ukrainian counteroffensive designed to liberate the southern Ukrainian lands seized by Russia, including Crimea, which provides Russia with a leading position in the Black Sea. And we could see the effectiveness of the Israeli air force almost live when fighter jets with Stars of David on their wings and fuselage leveled the Gaza Strip.
