I know of no one who complains about feeding, clothing, sheltering, providing medical assistance or assisting in any way the underprivileged here, there, or anywhere, on planet earth, fortunately. The discussion should be the fact those who need the aid and help many times never receive it when ruled by despots/dictators.
Military weaponry is very expensive but so is the cost of terrorists ruling/murdering others. Obviously, a country has to have a strong defense system since the world isn't exactly la la land.
