The Russians have promised an endless war to those who will dare to send their troops and support Ukraine with fighter jets. It is total panic, no one dares to send these armies to get Ukraine out of this threat. No one wants to give Ukraine warplanes for fear that Russia will anger and attack them too. It seems liable to Putin to see the containers of weapons landed in Ukraine of all kinds, javelins, stringers, anti-aircraft missiles of all kinds and battle tanks but not the planes of external powers and nor the trained troops of other countries.
