The West, geographically speaking, encompasses all of Europe. It was used as a term from the standpoint of the Middle East, for which Europe lies in the West.
Politically, the West is different to the cultural West. For example, Poland wasn't the West until they came in the EU, but now they can be considered so. Culturally, they have always been the West.
Sort of like how North-European countries are the West in spite of being North.
Good attempt at saying something rational, but not good enough! Do keep trying though!
