European allies are quietly shifting toward building their own intelligence capabilities rather than relying on Washington's, as they reassess their own vulnerabilities, according to an Atlantic Council dispatch published this week.

The intelligence-sharing architecture at stake was built by the United States over decades of partnership; the dispatch warns Washington risks being excluded from the very networks it helped construct if it fails to adapt.

This shift is unfolding amid intensifying Russian espionage and hybrid-warfare pressure on European states — the subject taken up this week by Estonian diplomat and columnist Harri Tiido, who turned to a former US intelligence officer for perspective on Moscow's spying operations, in a piece published by Estonia's public broadcaster ERR.

Hypothesis: the timing of these two pieces — a structural warning from a Washington think tank and a Baltic commentary seeking outside expertise on Russian espionage — suggests the question of how much to trust US intelligence-sharing has moved beyond Western European capitals to the states most exposed to Russia itself. Supporting this: Estonia sits on NATO's eastern border and has the smallest margin for error in any Russia-related intelligence gap. Against this: neither piece specifies what, if anything, Tallinn or other Baltic services are doing differently, so whether this reflects actual policy change or simply heightened public debate remains an open question.

What to watch: concrete steps — new bilateral or EU-level intelligence arrangements among European states, explicit statements from Baltic or Nordic services on reduced reliance on Washington — that would turn this reassessment from debate into policy, and whether Washington takes seriously the risk of being left outside networks it once anchored.
