We must understand the seriousness of this situation. The United States has made serious mistakes in the conduct of its foreign affairs, which have had unfortunate repercussions long after the decisions were taken.

Unqualified support of the Shah of Iran led directly to the Islamic revolution of 1979.

Then the United States chose to arm and finance the [Islamic] mujahedin in Afghanistan instead of supporting and encouraging the moderate wing of the government of Afghanistan.

That is what led to the Taliban in Afghanistan.
But the most catastrophic action of the United States was to sabotage the decision that was painstakingly stitched together by the United Nations regarding the withdrawal of the Soviet Union from Afghanistan. If you look at those matters, you will come to the conclusion that the attitude of the United States of America is a threat to world peace.
