Narva

Narva is separated from Russia by a river with the same name.

Some 96% of people in Narva are mother-tongue Russian speakers.

Estonia worries a confident Vladimir Putin might use the big ethnic Russian community in and around Narva as an excuse to invade.

Would the US, or even France, Italy or the UK, risk going to war with nuclear power Russia over Narva, a small part of tiny Estonia, on the eastern fringe of Nato?

When you travel to windswept Narva, in northern Estonia, you see why the country feels so exposed.
