Europe is yet again following the US on the basis of faulty intelligence and flawed reasoning. Even if claims that Iran has provided missiles to Russia were true, these sanctions would still be deliberately antagonistic and demonstrate an absurd double standard. Given that the West is the main supplier of weapons to Israel for use in the Middle East, it's the officials who imposed these unfair penalties that should be facing scrutiny.
There is more than enough evidence that Tehran has provided ballistic missiles and other weapons to support Russia's war effort in Ukraine to justify this move. There's no other way for Russia to explain possession of hundreds of Fath-360 close-range missiles, as well as Iranian-made drones. These sanctions are a welcome first step for the EU, but there's much more to be done.
