There are 3 such countries, called the Baltic countries. Estonia, Latvia and Lithuania. On the map, you can see that the 3 countries share a border with Russia. And the sharing of the border is quite significant. Because not only are these countries a part of the European Union, but a part of NATO also.
NATO stands for the North Atlantic Treaty Organisation. And it is a military alliance. It means that if a war breaks out against any NATO country, or any NATO country is attacked, the rest of the NATO countries would come to protect it with their militaries. Mainly the USA and the European countries are part of NATO, as I told you. The other military alliance on the Eastern side, was called the Warsaw Pact. But when the Soviet Union collapsed, the Warsaw Pact was also disbanded. But NATO’s existence continues even today. And 30 countries are part of NATO, in total.
The European countries have blocked Russia on one side, and on the other side, Japan is also a major NATO partner, In fact, Japan is a part of the G7 and the Quad Group as well. Russia has a long border with Finland as well. Although Finland isn’t an active member of NATO, but it has been a contributor to NATO-led operations. And on this map, look at Ukraine. Ukraine shares a long border with Russia. If Ukraine becomes a part of Russia too, Russia will obviously be pressured, because it is surrounded by all sides.
