Are we already in WWIII, even if most of us haven't realized it yet? Here's what experts say

Jamie Dimon , CEO of JPMorgan , said WWIII had "already begun," citing multiple conflicts in different countries.

Sir Richard Dearlove , former chief of the British foreign intelligence service MI6 , said there is an "actual war" underway with the Russians , albeit through non-military "hybrid conflict" The Ukraine war is already a global affair, as international partners support either side.

Peter Bergen : World War III has not begun, but with prudence on all sides, it could be avoided once again.

Nuclear weapons have made conquest among great powers impossible, he says.

He says major powers no longer need to compete hard to survive; they can ensure their sovereignty by maintaining a secure deterrent force.

The U.S. is secure from foreign foreign foreign powers, Bergen says.

World wars are cataclysmic events where majority of nations are officially at war and engaged in open warfare.

These are not the conditions of today .

It is more like the Cold War , where great powers are not fighting each other physically but are engaged in proxy wars.

The West is unlikely to send troops to fight in Ukraine , and most of the alleged Russian red lines short of direct intervention are unlikely to generate a military response.
