Russia abandons nuclear deal with new NATO member

Editor’s Note: This isn't just bureaucratic shuffling—it's a direct response to NATO's expansion. Russia has long warned against the alliance growing closer to its borders, and Sweden's membership was a red line. Ditching the nuclear deal could mean less transparency around arms control, raising risks of miscalculation or escalation. For Sweden, it's a sobering first test as a NATO member. For the rest of us, it’s another sign that Cold War-style brinkmanship isn’t staying in the past.
