sorry - but the WPA was created for a imminent threat like the Red Army pouring through the Fulda Gap. Not for disctesionary punitive expeditions which the Executive couldn’t get International agreement.
It’s abject lawlessness.
The Presidency was never considered to be a Imperial Autocrat.
Conservatives need to man up and support rule of law - especially when it’s difficult.
England and France were on board for this. That’s plenty of international consensus right there. Two fellow members of the Security Council, one of which is famous for its gun-shy attitude. The WPA is a tool. Different POTUSes use it as they wish. The Presidency IS imperial, but not autocratic. If Congress gets a bug up its nose about a particular action, it can and historically has, reigned POTUS in. That’s what the WPA was designed to do.
