In what appeared to be a message to spendthrift ministers, he warned: “There is no room for complacency. Our would-be opponents are investing billions. We have to step up or we will lose that advantage. We cannot let that happen.”

3. Spy games everywhere

U.K. Defense Secretary John Healey called reporters to Downing Street last month to condemn the “deeply dangerous” entry of the Russian spy ship — the Yantar — into U.K. waters. 

Britain deployed a Royal Navy frigate and Royal Air Force P8 planes to monitor and track the vessel, Healey said. After detailing the incursion, the U.K. Cabinet minister described it as a “stark reminder” of the “new era of threat.” 

“Our world is changing. It is less predictable, more dangerous,” he said.  

4. No way out

Healey’s deputy, Al Carns, followed up with his own warning last week that Europe must be prepared for war on its doorstep.  

Europe is not facing “wars of choice” anymore, but “wars of necessity” which will come with a high human cost, Carns said, citing Russia’s invasion of Ukraine as an example.
