If NATO's sovereignty in Ukraine is trampled recklessly by Russia, it will have no value in existence. What NATO does is to defend the values of democracy and freedom without hesitation, and must resolutely fight back against the robbers who savagely devour civilization and stop the destruction at any cost. Civilized behavior demonstrates justice, maintains international order, and guarantees everyone's normal and free life
Putin is seriously warning NATO to stay out and threatening much against them if they interfere. Now Zelensky is making video message to NATO to issue no flight zone around Ukraine and this will not allow Russia to attack them through the fighter planes and jet. Putin making also serious warning for that not to happen. The issue of no flight zone is the cause Zelensky is asking for and if that happens, I can't say what the dimension of the war.
