I know Congress needs to be involved to actually declare war, but there have been a number of times where something was kicked off by presidential authority alone.
If Biden wanted to, could he start a conflict against Russia without congressional approval. If not, what approval would he need? If so, what would be the theoretical limitations to his power and military authority?
I am already assuming people would want some definition of what “conflict” would mean in this hypothetical scenario. So let’s say it means Biden authorized US troops at the Ukrainian border and had them launching shells into Russia.
I mean in the literal sense the president is commander in chief of the armed forces. Disobeying their orders is defying their constitutional authority.
The issue is obviously more complicated than that just-so story. My point is not that if the president says to shoot the speaker of the house, soldiers must do it or they are behaving unconstitutionally. My point is that the president has the authority to direct the military to do things, and when the president uses that authority to undermine democracy in the US that act is a constitutional crisis because it pits two branches of government against each other in an irreconcilable way.
