How to extract the last (or only) line using a regular expression?

Question

excel

I have a table in Excel with a bunch of addresses like this:

Via Strada di Pontenuovo, 42
Santa Marinella (Rome)
Santa Marinella, Rome 00058
Italy

WA 98663
United States

Sri Lanka

From these addresses, I need to isolate the countries and put them in the next column. The country is always on the last line.

How to extract the last (or only) line using a regular expression?
