General Discussion

How, in your telling, does this SECOND article of the Constitution override the contents of the first one? (note: the Framers were very conscious of the order of these articles, putting the most fundamental principles ahead of others.)

If you accept that in your understanding, the two articles are in conflict, why does Article II get the deference?

And once more, show your work. You made an assertion--support it with actual evidence or STFU.

To your question about the military actions in three other cases, please be specific with dates and actions. I believe they were authorized by Congress under the AUMF. No further Congressional authorization would have been required.
