Discussing Iranian UAV transfers to Russia, National Security Advisor Jake Sullivan maintained: “The way that they are actually carrying them out physically makes physical interdiction a challenge. But we will not stop at a variety of means of seeking to disrupt this type of ongoing military cooperation and to continue to increase the cost to Iran – in the court of public opinion, with respect to economic pressure – for deciding to go down a road where their weapons are being used to kill civilians in Ukraine and to try to plunge cities into cold and darkness, which, from our point of view, puts Iran in a place where it could potentially be committing – contributing to widespread war crimes”.
