To be fair, the Dutch began hostilities by annexing Belgium.
Nope, that was a separate war that was already concluded with the Treaty of Brussels. When the Dutch marched on Belgium, the war was quick and decisive. No foreign powers (sans Prussia) involved themselves in any capacity, spare for France happening to be the place that Leopold ran off to.
This war began as a result of the Ottoman Empire declaring a blockade on Dutch shores, and moving ships into the North Sea to facilitate such a blockade.
