If I give you a region that is the namesake of a country, can you name one of the countries that own part of the region but is NOT the country that shares the region's name?
For example, India once owned East Bengal, West Punjab, Sindh, Balochistan, etc. but no longer owns these regions. These regions were once part of Greater India.
Start by naming any country that France borders. Then name any country that borders any of those countries. Then keep going until there are no more countries left to name.
