How do you make any judgment about historical events when you can't run concurrent A/B tests?

If America stayed home in World War 2, how do you know the Allies wouldn't have won anyway?

The writing was already on the wall in Europe when the US arrived. There is little chance the allies would have lost, just that all of Europe save probably for the UK, would have come under Soviet rule/influence.

They recovered while acting ethically - I think a better thing to ponder is whether the company would have gained more ground without the initial setback from pulling the product.

Though any speculation we have there is just that - pure speculation.
