No.
For some European countries they would need a visa.
Most European countries would have market economies.
The European Union is an organisation for countries in Europe, so the US could not join. There are over 50 countries in Europe, 28 of which are members of the European Union. There is no reason why the US would even want to join the European Union. It would make no sense for them to do so.
No European countries have a tropical climate. The closest to a tropical climate in Europe would be countries such as Spain, Italy, and Greece, which have Mediterranean climates with hot, dry summers.
Some European countries would have controlled parts of Asia, but never all of it.
The largest ethnic minority found in most European countries would be African.
Contiguous means connected, so the non-contiguous countries of Europe would be countries not located/connected to mainland Europe. This would only include island nations in this case: Cyprus Iceland Ireland Malta United Kingdom
Including all land of transcontinental countries, the three largest European countries would be Russia, Kazakhstan, and Turkey. Counting land only located in Europe, the largest countries would be Russia, the Ukraine, and France.
There is no such language as European. Europe is a continent with many countries and many languages. Each language would have its own way of saying faith.
Finland borders northeastern Europe (Russia). You could also argue that Germany (and possibly Austria) borders northeastern Europe for bordering countries such as Poland and the Czech Republic. Outside of Europe, Kazakhstan borders northeastern Europe, by bordering the most eastern part of European Russia. However, many consider Kazakhstan to span both Europe and Asia, which means it too would technically be a part of northeastern Europe.
Europe has many languages. There are over 50 countries in Europe. The different languages would have originated in different times and places and they continue to develop.
There already is a bank of Europe it's called the European Federal Bank and controls money supply and economic policy in all European Union countries which use the Euro as their country (including Austria).
