Can someone clarify why this question was asked in prelims 2025 ? Does upsc wants us to remember all NATO members ?
Q. Consider the following countries:
I. Austria
II. Bulgaria
III. Croatia
IV. Serbia
V. Sweden
VI. North Macedonia
How many of the above are members of the North Atlantic Treaty Organization?
A) only three
B) only four
C) only five
D) only six
@SubhashKshatri It's simple geo-location rule (wild-guess):
- Countries closer to Western Europe / surrounded by EU states - usually Pro-West (NATO)
- Countries in Eastern Balkans with historical ties to Russia - usually Pro-Russia or Neutral
- Austria
- west side, but known for neutral ideology - Not NATO
- Bulgaria
- Eastern Europe, EU-aligned, seeks security - NATO
- Croatia
- Balkan state, pro-West after Yugoslavia break-up - NATO
- Serbia
- Russia-friendly, militarily neutral - Not NATO
- Sweden
- Dropped neutrality after Russia–Ukraine war - NATO
- North
Macedonia - Small Balkan country, joined NATO for security - NATO
Current Affairs is the key here.
