Of course, thats not the only reason behind why the US is against their building of nucleur arms, its the agenda behind it too which is cause for concern.
I didnt say they boiled down simply to these factors in the first place. The myriad of issues you speak of, however, are a branch of these two main (but not sole) factors. The nucleur arms of Iran; Militarialistic aswell as foriegn policy. But my point is, whatever the intention (which isnt usually the case with other factors), a power matching up to the economic might or military might of a dominating superpower is certainly going to threaten them, be it because they feel their dominance is in threat of declining, or is in question, or for whatever other reason.How many countries do trade nuclear technology with? Officially and unofficially? The Pakistanis, the Indians, the Saudis and that is just the ones that the average American citizen knows about. We probably do business with a lot more people but don't publicize it. Yet who wouldn't argue that all this very trade in technology would threaten the U.S. if the radical factions in just a single one of these countries took over? No. My assertion is right. It doesn't boil down to 'economic and military power' it boils down to a myriad of factors that are a lot more complex than the general issues you present them as.
