"Flying in NATO reinforcements from Germany and Poland, which lie to the south, would be close to suicidal, Maj.-Gen. Neretnieks says, because of Russia’s formidable air force and the presence of long-range anti-aircraft batteries in Russia’s Kaliningrad exclave, which is wedged between Poland and Lithuania."

I hope someone in NATO has worked out the scenario of invading Kaliningrad to neutralize Russian forces there.
