F-16s can turn the tide of war under only one condition
The planes themselves can be an X-factor if you can flatten enemy air defenses and leave their aircraft on the ground. Well, like the Americans in Iraq. But such a function has not been delivered to us and will not be delivered.
At the same time, Russia, which started the war with total superiority in the air, was unable to overcome Ukrainian air defense and during the 30 months of the war could not make either aviation or missiles a decisive factor in the war.
But each plane, even if it does not lead to Putin’s surrender in 15 minutes, reduces the Russians’ ability to strike military and civilian targets with anti-aircraft missiles, allows more effective shooting down of enemy missiles and attack UAVs, reduces pressure on the front line, energy, and critical infrastructure in general.
