Russian President Vladimir Putin has thrown a dramatic challenge on the global stage by instructing officials to prepare for possible nuclear weapons tests. This is something Russia has not done since the days of the Soviet Union. Why now? It seems to be a strong response to US President Donald Trump's announcement to restart nuclear testing. This direction by Putin signals a shake-up in the cold and tense ties between the two world powers. While the move sounds like a loud thunder, Russia is also showing a softer side. The Kremlin has said it is "ready to discuss strategic stability" with the United States. This means Moscow wants talks to avoid dangerous risks and keep an eye on each other's moves, even with relations cooling rapidly. Putin's warning is a powerful message: the nuclear peace balance is shaking, and both sides are testing limits. Yet, the door for dialogue remains open, possibly to prevent a dangerous game of escalation. As both nations step carefully, the whole world watches with bated breath. Could this be a flashpoint or a moment leading to serious talks on arms control? The last time Russia (then Soviet Union) prepared for nuclear tests was decades ago. Now, history seems to be echoing loud once again. Will this nuclear chess game change the global security map? Stay tuned for more updates as the story unfolds.
