I've reported on more than 40 wars around the world during my career, which goes back to the 1960s. I watched the Cold War reach its height, then simply evaporate. But I've never seen a year quite as worrying as 2025 has been - not just because several major conflicts are raging but because it is becoming clear that one of them has geopolitical implications of unparalleled importance.

Ukraine's President Volodymyr Zelensky has warned that the current conflict in his country could escalate into a world war. After almost 60 years of observing conflict, I've got a nasty feeling he's right.

Nato governments are on high alert for any signs that Russia is cutting the undersea cables that carry electronic traffic vital for Western society. Their drones are accused of testing the defenses of Nato countries, while their hackers work to disrupt ministries and corporations.

Authorities in the West believe Russian secret services are responsible for the murders and attempts on dissidents living in the West. Recent inquiries into past attacks suggest involvement at the highest levels of the Russian government.

President Putin's response and the ongoing conflicts in Ukraine, Gaza, and Sudan have resulted in staggering civilian casualties — pointing to a year filled with unprecedented violence and instability.
