Russians Testing Frontier Air Defenses

This back-and-forth of military maneuvering, dating back decades, is a way for global powers to project strength and keep rivals on their toes.

In other words, it’s a game of flexing muscles without actually fighting. Both Russia and the U.S. do it—flying planes near each other’s borders, sailing ships through disputed waters—just to show they’re still in the game. It’s about seeing how the other side reacts, gathering intelligence, and reminding everyone of their military power without crossing the line into war. It’s an old tactic that goes back to the Cold War, and both sides know how to play it. Neither wants a full-blown conflict, but they still push boundaries to keep their rivals on edge.
