Russia warns NATO over 'provocative actions', cites nuclear use as reminder

The Russian embassy in Brussels issued a document expressing concern over NATO's 'provocative actions' and reiterated nuclear use warnings as a deterrent to 'hot-headed' Europeans. This follows a pattern of escalating rhetoric, but the specific reference to nuclear use in a diplomatic note marks a notable hardening of tone. The development signals heightened tension between Russia and NATO, though it remains unclear if this precedes any concrete military escalation.
