Happiness, the examples you cited don't want war. War ruins the market. What they want is for the pot to keep simmering but never boiling over. That way, the antagonists keep buying the latest in weapons systems so they can have the very latest in defense/offense.
And the gunrunners supply the little guys like Hezbolla and Hamas.
