Christianity is not Right or Left, nor is it Nationalist or Globalist. If you look at the teachings of the Church, which itself is informed by even older Jewish tradition and the idea of Natural Law (which lines up pretty well with the Ten Commandments, by the way), you will find that the Church is actually pretty centrist. The Church does not take sides with political parties or governments, but it is certainly not indifferent to the condition of men and the ways in which government, for good or ill, affects them. There are things various governments have done or tried to do that the Church specifically spoke out against, because they were harmful to the people living under those governments.
Fundamentally, the Church believes that governments should work for the benefit of their nations (the people), but it doesn’t say how that government should be organized. If anything, it says that different nations may find different ways to be governed, and that’s okay. Certainly you will find very different sorts of governments as being compatible with the Catholic Church if you go back through history.
Since you asked specifically for some books, I suggest you find a copy of The Popes Against Modern Errors: 16 Papal Documents, which contains (you guessed it) 16 papal documents attacking various errors in social and political movements from 1832 to 1950. It’s not the easiest read, and arguably not all of it is about politics, but it will give you an idea of the sorts of things the Church doesn’t like to see going on in various nations.
