Last time there was a war with Iran was when our Western governments asked our then friend Saddam Hussein to please invade this country.
Didn't work, and more than a million young men were killed uselessly.
Just because Israel wants us to invade Iran doesn't mean that we have to.
Hazing of new recruits was a common thing in the French Armed Forces until conscription was abolished a decade ago. Almost all of us had to go through it, and it could be VERY unpleasant. I don't know about professional soldiers today, and even less about the situation in the US.
