You are missing the point. Congress funded those operations AFTER the fact, when the military was already committed.
Here is the restriction I think you are trying to reference (since you can't bother to look up information to back up your opinion):
"The War Powers Resolution requires the President notify Congress within 48 hours of committing armed forces to military action and forbids armed forces from remaining for more than 60 days, with a further 30 day withdrawal period, without a Congressional authorization for use of military force (AUMF) or a declaration of war by the United States. The resolution was passed by two-thirds of Congress, overriding a presidential veto.
It has been alleged that the War Powers Resolution has been violated in the past – for example, by President Bill Clinton in 1999, during the bombing campaign in Kosovo. Congress has disapproved all such incidents, but none has resulted in any successful legal actions being taken against the president for alleged violations". -https://en.wikipedia.org/wiki/War_Powers_Resolution
So the president can fully commit our military for 90 days without authorization from congress, plenty of time to invade / conquer / destroy a nation with our current military resources (approved budget of $680 billion, this does not include the supplemental budgets, which is what you are referring to). Afghanistan - government overthrown within Oct - Dec 200, less than 3 months, mostly done within a month. Iraq - government overthrown within 3 weeks of major combat operations. The thing that takes time is rebuilding and 'keeping the peace'. Those two examples, were also approved by congress, but that doesn't really matter, because he could have done it without them. Vietnam & Korea are better examples, or the lesser known Kosovo, Syria, Nicaragua, and broad cold war, but they are probably unfamiliar to you, because I'm guessing you are young.
The supreme court has little to no effect on military operations.
Read up on history kid, your ideological beliefs (however much I wish they were true) do not mirror reality.
