Near the border where Ukraine meets Poland, Russia struck a rail junction that has quietly become one of the war's most consequential arteries — the passage through which Western resolve flows into Ukrainian resistance. Officials on both sides of the alliance read the attack not as a tactical maneuver but as a deliberate communication: that the cost of solidarity has an address, and Russia knows it. The strike marks a maturation in Russia's strategy, one that targets not just territory but the political will binding Ukraine to its supporters.
