Incidentally, why do you use quotes instead of quote-markup with '>'? It's a bit harder to read.

Agreed, but there's still peace in Europe in this scenario.

Yes, because of US hegemony.

"Corporations" do not act coherently like a national government does. There is no "United Corporate Alliance" or any such thing.

There would be if 90% of all corporations had a common cause that was a life or death matter for them! At the very least all the corporations would be pushing in the same direction, and even without a formal alliance the result would be much the same.

Some would, but some would probably push for it (military contracting can be enormously profitable). There were certainly plenty of companies that pushed for a US war in Iraq.

Companies benefit from war - if they expect to be on the (economically) winning side, and if war isn't going to occur on their home turf. If US companies really honestly believed there was a 50-50 chance of Iraq winning the war and conquering New York, none of them would have supported a war.

In Europe, too many big companies are multinational. All of them stand a lot to lose from an internal war. Also, in a war they would have to bet on winner(s) right at the start - because if they want a military contract with Germany, then Germany's going to demand they stop selling weapons to France.

In WW1 the big economical winners were US companies because they sold everything but actual weapons to the Alliance countries for many years without being directly involved in the war.
