what were 3 issues that led to hard feelings between the soviet union and united states

During the Cold War, several issues contributed to strained relations between the Soviet Union and the United States. Here are three significant factors:

1. **Ideological Differences:**

  - **Communism vs. Capitalism:** The ideological conflict between communism (espoused by the Soviet Union) and capitalism (embraced by the United States) was a fundamental source of tension. The two superpowers were driven by conflicting political and economic systems, each viewing the other as a threat to its way of life.

2. **Nuclear Arms Race:**

  - **Arms Buildup:** The nuclear arms race, marked by the development and stockpiling of nuclear weapons, intensified the rivalry. Both nations sought to outdo each other in terms of military capabilities, leading to an atmosphere of mutual distrust and fear of a nuclear conflict. The Cuban Missile Crisis in 1962, a direct confrontation over Soviet missiles in Cuba, brought the two powers to the brink of nuclear war.

3. **Geopolitical Struggles:**

  - **Expansion of Influence:** The United States and the Soviet Union competed for influence in various regions around the world, engaging in proxy wars and supporting opposing factions. Conflicts in Korea, Vietnam, and other areas exacerbated tensions. The U.S. policy of containment aimed to limit the spread of communism, while the Soviet Union sought to expand its sphere of influence.

These issues, among others, created a hostile geopolitical environment characterized by the ideological, military, and geopolitical competition between the two superpowers. This state of affairs persisted for much of the 20th century until the eventual thawing of relations in the late 1980s and the eventual dissolution of the Soviet Union in 1991.
