NATO Troops stationed (oh, on annual Exercise) in Poland and at most of the military bases at this moment.
Poland breaks European Treaty on unilaterial deployment of soldiers outside their national boarders - clearing the way for Western Ukraine.
Putin warns he will strike planes taking off and landing who attack Russian forces or Russia anywhere they exist (The F16 Airfield was blown up a week ago, along with the command center, all the parts and inventory for the aircraft,and all the fuel storage nearby).
Germany tells Macron that NATO Art 5 will not save them or be triggered if France sends troops to Ukraine. Cited Putin warning to attack those fighting Russia wherever they exist.
Polish Troops participating in NATO exercise begin to disengage for deployment to Ukraine.
Poland will become a party to the war and be attacked if they use their troops and/or airfields. NATO has about 60,000 troops in Poland to ensure they can trigger Article 5 if Russia retaliates.
Romania offers Ukriane her Airfields for the stationing of F16s for combat operations. NATO sends troops to airfields.
Looks like NATO is pushing Putin on his claim to attack enemy aircraft wherever they exist, land, take off.
Of course Poland has NATO troops in it, being a NATO country.
When President Trump reactivated the American V Corps he moved its permanent European Headquarters forward from Germany to Poland, closer to the Russian threat.
