The answer is:

All of these countries have red, white, and blue flags.

Here's the list of question marks (in order):

Cambodia, Czech Republic, France, New Zealand, North Korea, Norway, Samoa, Taiwan, United Kingdom, United States

Here's what I think your source was:

http://en.wikipedia.org/wiki/List_of_flags_by_color_combination#Blue.2C_red_and_white, and in this case it seems like Costa Rica may not count.
