Adding and Dropping Columns II

I have this table in my SQL Server 2022 database:

CREATE TABLE [dbo].[CityList]
(
[CityNameID] [int] NOT NULL IDENTITY(1, 1),
[CityName] [varchar] (30) ,
[Country2] [char] (3),
[stateprovince2] [char] (2),
[Country] [char] (3),
[stateprovince] [char]
) ON [PRIMARY]
GO
I decide to drop the stateprovince2 and country2 columns. What code should I use?
