The same comment I had to Rn.
He didn't write them since he was already dead, even staunch reformed scholars of today realize that the remonstraters didn't replicate Arminius' own ideas, their claim wasn't against the reformation but for acceptance of theology that had been acceptable under earlier confessions, and Molinist conspiracy theory ignores Arminius' detestation of the papacy due to the murder of his family by the King of Spain's minions.
Let me ask you this simple historical question: "During this era, why did the King of Spain invade the Netherlands?"
