What were the psychological effects on the soldiers of World War 1?

Yes only if you know where to look a first time Visitor to berlin would Know about WW2 so would be aware of what we the RAF did to berlin such a shame that the cities and towns had to be destroyed nut the Berlin cathedral was almost intact as was the Cologne Cathedral and Only a back wall of St Paul's Cathedral was Damaged and there are Hundreds of Churches in germany still left intact I was in Germany after WW2 with the RAF and germany was like london a Bombed site I did my first visit to berlin in 2007 and there is a lot of open green space that was not there in 1939 one of the Designers of berlin loved the Champs-Élysées paris he wanted Berlin to look similar and there are some of the remains along Unter den Linden a tree lined Boulevard but with only about 42 of the Original corner Buildings the old street lights have been made New bit occasionally you will see an old fire fighting pump still in place about 85 % of berlin was destroyed I remember railway stations covered in Bullet holes look at any Movie of the Russians Taking the Reistag and look at it today you can see the Repairs to the Facade I love Germany and was lucky enough to have been posted to a place called Jever top North western point of Germany near the Dutch Border the Town was saved from destruction as was the Luftwaffe base when the Town and the Military agreed to surrender the town to the allies well worth a visit to see a post war town as it was before there are smaller towns But from the Movie the Bridge at Remargen the Bridge has gone But the Tunnel either side are still intact.

This is a big question, and I'm sure you could approach it from several different angles - economically, socially, landscape, politically, etc. I lived in Germany for several years, right around the time the Berlin Wall fell, and have maintained contacts there. I can tell you that there are certainly social and political echoes, though these are more often hushed tones, as people worry that their opinions could be misconstrued as Nazi-friendly. Germans, especially those old enough to have lived through World War II and the aftermath, are afraid to be viewed in this negative light, so they sometimes err on the side of political correctness.

There are still landscape remnants, too, although the German government will often demolish a historical site because of the perceived (and often misguided) opinion that some neo-nazis will come out of the woodwork and hold pro-Hitler rallies. (FWIW, in 5 years living in Germany, I never saw any hint of neo-nazis - only the accusations of those on the opposite end of the political spectrum to hush opposition).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
