I wouldn't imagine he lives a particularly luxurious life, either, even if its a very expensive one.
There are definitely some wars I'd much rather were just MMA death fights between the PM's and presidents.
And others where I'm glad they aren't, because the country whose victory would be best for the common good is led by someone who would not win a physical fight.
