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.
He could do it for 60 days, at which point to legally continue, Congress would need to authorize an extension. A declaration of war is unnecessary, but an authorization of force (which is let’s call it a more polite euphemism for the same end effect) is at least.
Continued military operations beyond that time would trigger a big political mess. As a practical matter, military forces would still most likely follow presidential orders while the president was either forced to order an orderly withdrawal by Congress, or Congress gave in and retroactively authorized force (either a limited authorization to allow an orderly retreat or a more open ended one for a continuing military posture).
If the political situation was intractable, you’d likely be looking at an impeachment hearing.
I would be really interested to see how it plays out if Congress decided to try and put the pin back in the president’s grenade. Would the US be forced to pay reparations? Would the military industrial complex flex its own political muscles more overtly than ever? How would that pan out in elections?
You raise interesting discussion points, but I’m tired, so I’m going to engage in them by way of memes.
The questions were rhetorical but yeah
