Jimmy Carter's policy towards the USSR involves sanctions and boycotts in an effort to discourage the invasion of Afghanistan and improve US influence in the Middle East.
During his state of the union address, President Jimmy Carter announces that any attempt by the Soviet Union to control the Persian Gulf's oil supply will be perceived as a threat to US interests and be met with consequences.

America decides to ramp up spending on aid to the Mujahideen so that they can fight against the Soviets. They increase the budget to approximately 3 billion dollars and start sending STINGER anti-aircraft missiles to attack Soviet helicopters and planes.
