No it's not. They came up with the interpretation that the https://en.wikipedia.org/wiki/War_Powers_Resolution allows them to engage into limited armed conflicts without Congress authorization. Which is dearly needed, because that's what they are doing since decades, with the CIA and friends. And several such CIA wars happened even without the President's authorization, but usually the just lie to the president to able to engage in such armed conflicts.

What this War Powers Resolution does not authorize is a formal declaration of war (Clinton did not care) and any engagement voiding the Geneva conventions. All those drone killings are of course war crimes. This is one of the reasons the US does not recognize international law.
