I wish we had the paradigm of 1991 in place still. Massive and exceptionally advantaged technologically, actually worried about outcomes and knock-on effects of disrupting current order, allies lining up to pay into a common fund for collective security, upset at killing civilians, Vietnam miasma in rear view mirror as a warning to not do that. Add in these elements:
Sober as f SecDef - as opposed to guy who needs to show you how many push ups he can do between shots
POTUS schooled in noblesse oblige and who had actually been shot down in a shooting war - as opposed to a guy who rapes children
Chairman of the Joint Chiefs schooled by life as a small unit commander in Vietnam and the inventer of the weinberger doctrine - as opposed to whatever yassir we got now
