I recall hearing the biggest impediment to a Mexican invasion of the US is arms. Is this right? If this is true, than perhaps if Germany had a naval victory, at least enough to break the blockade, the could deliver arms to Mexico.
Another idea is if the US joins the war, but Germany still defeats France, would Germany (assuming they had the naval ability in this scenario) send tropps/arms to Mexico to knock the US down a peg or two?
