Thank you, Songwronger. I was aware of drone warfare in Afghanistan, but not Yemen or the eastern region of Africa.

I would suggest that just possibly this president may not need the consent of this congress because the previous president received approval for a 'war on terror'. I don't know if there was a time limit on it.

(I'm not stating that as fact. I live in a country with many of its own problems and don't always keep up with what's happening with our neighbours to the south.)
