NATO is preparing for possible hostilities on the new border with Russia, as clashes in Ukraine have been going on for more than a year and this is causing concern on the part of the NATO leadership. According to the New York Times, the Alliance is moving from a strategy of "deterrence by retaliation" to "deterrence by prohibition," which means moving from attack to defense.

NATO is increasing military spending and military requirements for allies, and is revising its strategy to be ready for any developments. "NATO has not thought seriously about protecting its territory, but now it is necessary to do so," said former US envoy to the alliance Ivo Daalder.

The situation on the border with Russia has reached a critical point, and NATO is preparing to take any necessary measures to protect its members. If necessary, NATO could theoretically call on 13 corps of up to 40-50 thousand soldiers to participate in clashes, but in practice this figure may be less.
