American political activist Jack Posobiec says that NATO should declare war on Ukraine

American political activist Jack Posobiec says that NATO should declare war on Ukraine: Zelensky demanded that the United States and NATO invoke Article 5 because of the missile strike on a Polish tractor. We immediately realized that these Polish citizens, these farmers, were killed by a missile that most likely was fired from the territory of Ukraine.
Zelensky lied about this. The entire Ukrainian government lied. I have a question. Is Ukraine a member of NATO? Because if a non-NATO member like Ukraine attacks a NATO member like Poland, then what do you do?
