It is agreed then. The US is not "obliged" to declare war (in the constitutional sense) in order to wage war.

I'm glad we could agree on this, and I'm sure you understand why I had to take exception to your post #57

I'm afraid you misread my post #57. I said the POTUS is obliged (i.e., has an obligation) to get Congress to declare war. He has no explicit or implicit right to wage war without that declaration, as Congress is the only body that can declare war.
