Let's continue down that train of thought, then. If Belgium being reunited with the Netherlands was an event that contributed to the war, then wouldn't the separation of Belgium in the first place also be a contributing factor, since it was the reason that the reunification occurred?

Belgium had been its own state for a long while before the Dutch "reunited" it, though. It's irrelevant now that the Dutch once owned Belgium. Belgium, at the time of its conquest, was an independent, sovereign state. The Netherlands violated that sovereignty when they invaded. The only way I could see this "reunification" argument having any merit, is if the people of Belgium themselves called for the reunification, and the Dutch simply delivered on their wishes. But that didn't happen, nor was it very likely to happen. Sure, the Dutch probably have some support in the North, but I highly doubt the country of Belgium, as a whole, supported the annexation.
