capitalism produces wars, but it can't be said that war in general was a product of capitalism specifically. War is a product of class society, not just capitalism. Wars ie. armed conflicts between considerably organised bodies of men have occurred constantly throughout the history of class society (slavery, feudalism, capitalism).

US war against Iraq is an example of one type of war common in the era of imperialism; neo-colonialist war. Redivision of markets, exportation of capital to raw material resources.

The politics of US government is not primarily a matter of lobbying, though that also has its part. USA is a highly developed society of state monopoly capitalism. Serving finance capital (serving the rest of bourgeoisie is secondary, which makes libertarian "anti-state" sentiments attractive to the middle-capitalist and the petty bourgeois) is the very function of US government (and the governments of all state monopoly capitalist societies, including Finland).

As imperialism is the main source of modern wars, liquidation of imperialism is the top prerequisite for world peace.
