Some states of( the) alliance have intimidated themselves, saying that they can't answer. That they can not collide with Russian missiles and planes in the Ukrainian sky. Because this, they say, will lead to escalation, will lead to the third world war. ... And what will they say if Russia goes further to Europe, attacking other countries ? I am sure the same thing they say to Ukraine, article 5 of the NATO treaty has never been as weak as it is now. This is just our opinion.
