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 nearly 60 years of observing conflict, I've got a nasty feeling he's right...

The year 2025 has been marked by three very different wars. There is Ukraine of course, where the UN says 14,000 civilians have died. In Gaza, where Israel's prime minister, Benjamin Netanyahu promised mighty vengeance after about 1,200 people were killed when Hamas attacked Israel on 7 October 2023 and 251 people were taken hostage. Since then, more than 70,000 Palestinians have been killed by Israeli military action, including more than 30,000 women and children according to Gaza's Hamas-run health ministry...

In the coming year, 2026, does look as though it'll be important. Zelensky may well feel obliged to agree to a peace deal, carving off a large part of Ukrainian territory. Will there be enough bankable guarantees to stop President Putin coming back for more in a few years' time?

Even if President Trump loses a lot of his political strength at next year's mid-term elections, he may have shifted the dial so far towards isolationism that a more NATO-minded American president in 2028 might find it hard to come to Europe's aid...

The outlook could scarcely be more gloomy. If you thought World War Three would be a shooting match with nuclear weapons, think again. It's much more likely to be a collection of diplomatic and military manoeuvres, which will see autocracy flourish.
