Sweden is not "neutral" v-a-v Russia. Although Swedish discourse wrt Russia and NATO differs somewhat from that of Finland, there is no policy of "neutrality" wrt war or comparable crises involving eg. Russian aggression against states that Sweden is committed to support; instead, there is an official policy of solidarity, which includes military support. In several respects, NATO-Sweden relations are similar to—but deeper and more well-established than—NATO-Ukraine relations.
