I honestly believe you’re right. People say it must be the horrors, but my guess is that today’s horrors of Afghanistan, Iraq, etc. were/are no more than WWI, WWII Korea, or even Viet Nam.
The difference is ROEs, hatred of our military by Democrats (well, they did this during VN, too), and a determined purpose to demoralize and debauch our military.
Frankly, if my son, or daughter, or grand children wanted to join our military, I’d advise them NO.
My 90 year old dad was in Battle of the Bulge - he STILL has nightmares. He has had several panic attacks while hunting out in the woods when there is snow on the ground. He still won’t talk much about the war, but says that during The Bulge he didn’t have any idea where the enemy was, he couldn’t even trust men he didn’t know after seeing one of his buddies killed by an infiltrator in a U.S. uniform.
