This comment just shows you to be ignorant and contrarian.
And recent research absolutely has shown that heavy cannabis usage in adolescence and early adulthood does have a clear association with an increased risk of developing psychosis and schizophrenia. Just because the war on drugs lied about the effects of less harmful drugs like cannabis doesn’t mean they can’t be hazardous to your health like any other substance.
Regarding heroin - one may not be particularly murderous while zonked out, but addiction can make people surprisingly aggressive.
I’d also like to add that the company-grade officers stuck in the mud alongside enlisted were less at fault for the needless deaths than the incompetent general staff or the political actors who got us and kept us over there in the first place. You might enj the novel “Matterhorn” by Karl Marlantes, a Marine infantry officer who served with distinction in Vietnam. Or you might prefer “Dereliction of Duty” by Lt General H.R. McMaster, a renowned commander of the GWOT era who wrote his PhD thesis on the failures of Westmoreland and the other generals who mangled Vietnam.
I think the original reason for requesting the high-school diploma is two fold. On one hand the person can come back and pick up where they left off, with a better chance of serving society. But maybe the more important one was that it lowered the chances of teens enlisting it the pit of desperation, seeing themselves as failures, with no other way out. Those may not be the people you really want because those may not be the people who really want you. This is the kind of deal that's hard to pull out of, and the Army would probably not want to be in the situation to have a wave of desperate teens realizing they just made a rash decision. The Army also doesn't want to be drained of new recruits, so here they are, taking what's on the table. It's a clear sign that young people are sending to the Army though.
You’re saying that the US military has issues and it may well have. I’m no expert on that. But I still believe that a person who has dropped out of high school has a lot to offer society. It seems like the US military is coming around to the same line of thinking, as long as the person passes the IQ test. I think that’s a reasonable compromise.
The program might fail but if we never try then we’ll never know.
