Will NATO's "victory theory" work?
The alliance offers a shared vision for deterring adversaries.
NATO says it does not want war, but it is ready for war.
The message was delivered by its top military commander as he drew up a new plan to defend his territory.
This includes low-cost drones, artificial intelligence and rapid strikes to prevent any potential attacks on member states.
NATO has undergone a strategic shift after the United States announced it would withdraw thousands of troops from Europe.
But this is only one of the factors that lead leaders to increase the military budget.
They also worry about what they say is a growing threat from Russia.
