NATO will deploy a permanent full-scale military force on its border with Russia

NATO will deploy a permanent full-scale military force on its border with Russia to defend its territory against a future Russian invasion, the alliance's chief said during an interview with The Telegraph.

NATO Secretary-General Jens Stoltenberg told the newspaper that the alliance was "in the midst of a very fundamental transformation" that will reflect "the long-term consequences" of Russian President Vladimir Putin's actions.

"What we see now is a new reality, a new normal for European security," Stoltenberg said, per The Telegraph. "Therefore, we have now asked our military commanders to provide options for what we call a reset, a longer-term adaptation of NATO."

The alliance currently has a small "tripwire" presence to the west of Russia. NATO troop numbers have increased tenfold to 40,000 since the invasion of Ukraine, The Daily Mail reported.
