It's no wonder so many countries throughout the world dislike or even hate America. We are constantly interfering in the internal matters of other countries. Often when the matters don't even affect us, as in Ukraine or even Syria. Sanctions will only worsen our relationship with the only country in the world that could possibly challenge us.
The US is not the World's policeman. We need to learn to mind our business and stay out of any matter that doesn't concern us or our allies. At the very least, UN Security council authorization should be a requirement for our involvement in these type of conflicts.
