Answer:
The correct answer is D) The Soviet collapse caused governments like Iraq and Iran to behave more erratically.
Explanation:
During the cold war period both Iran and Iraq were closely aligned with the Soviet Union. In Iraq, the Ba'ath Party had swept to power and was based on socialist and secular values.
In Iran, the Islamic revolution had brought into power, men who were against American influence in the region.
Being close to the Soviet Union provided them with significant support in terms of trade, economics and military support. However, with the fall of the Soviet Union, this support almost evaporated overnight.
After this, the international relations of these countries became even more difficult and they began to behave erratically.
