Of course, God has decreed the gospel to be preached to all the nations, that whosoever believes will be saved. Scripture simply explains why any particular man believes or does not believe and Calvinism has exposed that truth.
1 John 2, propitiation for our sins and for the whole world, is simply for the believeing world ALONE who has their sins propitiated from the jews and from the gentiles, who make up the whole world. The unbelieving world does not have the propitiation of their sins. Propitiation means the appeasement of wrath of a deity, and obviously they experience the wrath of God, so they do not have the propitiation do they.
No appeasement of wrath, means no propitiation of their sin. etc.. These here are some people who experience God's wrath.
