Why is it so hard for the U.S. to win wars?

The U.S. has struggled to achieve quick victories in conflicts like Afghanistan, Iraq, and Iran, despite promises of swift and decisive outcomes. These prolonged engagements have failed to meet the initial political objectives, raising questions about the effectiveness of military strategies and the complexities of modern warfare. The challenges highlight the difficulties of applying conventional military force in asymmetric conflicts where political, cultural, and local factors play a huge role, underscoring the need for a more nuanced approach to warfare.
