Estonian intelligence head flags major Russian buildup along NATO's eastern flank

Estonia's foreign intelligence chief says Russia plans a major buildup along NATO's eastern border—potentially doubling or tripling prewar forces—depending on the Ukraine talks' outcome, with Moscow keeping substantial units in occupied Ukraine and on its side of the border. There are currently not enough resources for a full attack, but Moscow fears European rearmament and remains convinced it can outmaneuver the United States. US-backed talks are described as constructive but have yielded no breakthrough, and the conflict could persist for years.
