The relationship between the U.S. and Russia has been complex and often tense since the end of the Cold War in the early 1990s. Both countries are major global powers with significant military capabilities and influence in international affairs. Their interactions have included cooperation on issues like nuclear disarmament, but also conflict over matters such as Ukraine and Syria. In recent years, tensions have escalated due to allegations of cyberattacks, election interference, and differing views on global security. Diplomatic efforts continue, but challenges remain as both nations navigate their interests and historical rivalries.
