Russian military operations remain concentrated on Ukraine, with recent large-scale drone and missile strikes on Kyiv and other targets in mid-May underscoring continued escalation in that theater rather than direct moves against NATO territory. Intelligence assessments from European agencies indicate Moscow is reconstituting forces and could pose a regional challenge to the alliance within roughly one year after any Ukraine ceasefire, primarily through limited territorial probes or hybrid actions aimed at testing alliance cohesion. NATO allies continue to coordinate additional long-term military support for Ukraine while conducting exercises that highlight vulnerabilities in drone defense and Baltic-region defenses. Upcoming factors include potential force reallocations once Ukraine fighting subsides and ongoing diplomatic efforts to sustain Western aid commitments.
