This agreement is about America's national security interests. By ensuring that Iran doesn't have the capacity to develop nuclear weapons, the world will be a safer place, and the Middle East may be able to enter a long needed period of relative stability.
While the world is focused on the invasion of Ukraine, President Biden is working alongside Russia to enter back into this bad deal, which, in fact, increases Iran's nuclear capabilities and threatens America's national security – not the opposite.
Russia is one of the negotiating parties and its requests must be received and fairly considered. Iran's peaceful cooperation with all parties shouldn't be limited by sanctions imposed without UN approval. Russia and Iran have the right to trade, investment, and military-technical cooperation unhindered by the West.
