Time is of the essence. Ukraine are the good in the fight against Russian President Putin’s invaders.
The tank convoy growing is excellent.
To really make a faster difference however aircraft into Ukraine is needed.
Type of aircraft between different nations is up to them but preferably ones with minimal training.
By Ukrainians who already have training.
Otherwise the war will only spread outside of Ukraine. There will be no more Europe then. And a start of WWIII. That cannot happen. Europe, the West and the East must get aircraft to Ukraine.
Japan in the East are a big player in this regard surely. Others too such as America.
No need to talk about it just calmly execute.
