Lifting sanctions on Iran...
"Iran has embraced Russia’s
anti-Western narrative over Ukraine, portraying the intervention as a harbinger for the West’s decline. Tehran’s proclivity to capitalize on Moscow’s discontent with the West was apparent in Raisi’s
speech to the Russian Duma in January, which devoted significant attention to condemning NATO “aggression.” Official
statements and state-linked
media outlets have been largely sympathetic to the Russian side, a notable shift from internal divisions within Iran surrounding
Georgia in 2008 and
Ukraine in 2014"
Possibly the biggest danger from this whole situation is that if, as Boris Johnson and others on this thread are calling for,Russia is fought back to its own border by Ukrainian troops ( however unlikely that might be) then rather than Putin using his nuclear option he may just supply Iran with enough atomic material for them to attack the West via Israel.
