I'll help you hope as well that power won't just rely on the amount of regiments one can field. The Dutch republic was always a prime target for all of its rivals both on and off the continent, but I think one of the main reasons why neither France nor Prussia ever really succeeded was because the relationship with Prussia was reasonable due to marriages and France was never able to succesfully occupy the economic heart of the country, which was protected by a series of fortresses and land that was flooded in case of war..
Louis XIV and his German allies managed to capture most of the Netherlands in 1678, but had to withdraw because the English fleet was destroyed when it tried to launch an invasion of Holland and the French and German armies weren't equipped or meant for occupation of large parts of the country..
The only time the French managed to capture the Netherlands was (surprise, surprise) when a heavy winter struck and the Water Line froze over, allowing their armies to cross into the heart of the Republic as if there was nothing stopping them..
Unfortunately I doubt the Empire:TW developers will go so far as to give such an ability to the Dutch, so I fear that (right from the getgo) it'll require a lot of diplomatic and military skill to keep the predators away. Searching for a powerful ally right from the start would probably be best (and I fear the best candidate for that would be France)..
That is a given.. If they're not in there, they will be in there as soon as I decide which faction to replace with the Dutch..
