To be honest, you are scarring me. Poland step in? Is that even a serious consideration among Poles? Yikes. Your comment sent willies down my back.
Why not, I think that Ukrainians will do it without our help but if situation would be really, really heave polish government have my full support. We aren’t the French, to only watch and do nothing. If something like that would happen, I think that Ukrainian troops would surrender immediately, for what they would have to fight? Generally even NATO should do something, in another way we should remove this organization as unnecessary.
