Hanukah is a Jewish holiday and there is only one country where the majority of the population is Jewish--Israel. Hanukah is celebrated in many other countries, but only by individuals in those countries who are also Jewish. Actually,there probably aren't that many Jews who really celebrate Hanukah like American Jews do since it is a minor holiday. American Jews have made a big deal out of it because it comes at the same time as Christmas and it helps them not to feel left out.
