I think Napoleon likely would have allied with the US over the long term. The US did not have the baggage of nobility, was ruled by enlightenment thinkers, and we already had a common enemy in the British. That said, the US was a sparsely-populated backwater outpost at the time with only about 7 million inhabitants (a million of whom were slaves). For comparison, the population of Europe during the same time was close to 140 million. We simply didn't have the manpower, infrastructure or money to meaningfully contribute to a European conflict at the time.
