The Republic of Malta is the smallest microstate worldwide.
Explanation
The statement "The Republic of Malta is the smallest microstate worldwide" is false. While Malta is a small island nation in the Mediterranean, it is not the smallest microstate in the world. There are several smaller microstates. For example, one of the smallest microstates is Vatican City, an independent city-state enclaved within Rome, Italy. Other examples include Monaco and San Marino. These microstates are characterized by their small geographical size and often have unique political and cultural characteristics. Malta, though small, is not the absolute smallest when compared to some other microstates.
