I agree with what you wrote about politics. Most political parties are essentially the same thing, and only focus on small differences. I also agree that abroad you might end up being friends with people from your home country just because you are from the same country. I lived abroad for 7 years and I found that people who hang out with compatriots have a hard time integrating into the new culture later on. I tried to avoid this. Although you will be lonely at first when you do meet locals it will be much easier.
