Summary
US allies including Israel, Saudi Arabia, and Five Eyes members are considering scaling back intelligence sharing with Washington due to the Trump administration’s warming relations with Russia.
Allies fear compromising foreign assets’ identities. Sources with direct knowledge confirm “those discussions are already happening,” though no decisions have been made.
While the UK, Canada, and Israel publicly affirmed their intelligence partnerships, former US intelligence officials express deep concern about Trump’s Russia pivot.
Previous US attempts at intelligence cooperation with Russia historically failed.
In practice there is no way non-US intelligence agencies are sharing intelligence that is critical to their agents’ safety or national security with the US. I doubt they ever have shared that intelligence with anyone, save in very discrete circumstances. In public they will continue to pretend that they’re sharing, as they have always done.
