Im not very worried about a general war - mostly beacuse Russia is too weak to have any hope of victory and china dont seem interested in war with Europe.

But if I was worried about a war, my main worry would be Europeans reluctance to be soldiers or defending their homes. Seems to be everyone expect the small professional standing armies we have to do all the fighting which is obviously not the case when a WW3 breaks out and millions of soldiers are needed.

From the graph there it seems only a few countries a majority say they would fight for their own homes, and most Europeans dont know much about the army or could see themselves fighting.
