Their quite weak army might be a problem. Finland had this problem, among other problems, but built up its army in the last 50 years, little by little.
The Finns have always made up in quality for what they lack in quantity.
There's an old joke from the Winter War, which I am sure you have heard, but which bears repeating:
A Russian General is inspecting the front line, and hears a voice from behind a snowdrift "One Finnish soldier can beat ten Russians!"
Incensed by this cheek, the General immediately orders ten soldiers to go and bring back the Finn, dead or alive. The detail disappears behind the snowbank, and the sound of a fierce struggle can be heard. Then, silence.
And then the same voice calls out "One Finnish soldier can beat fifty Russians!"
The General is enraged. He orders fifty men to go and get the Finn, with orders to kill him on sight, and bring back his body. The Russian soldiers once again disappear into the snow, and once again, sounds of intense battle can be heard. Then, silence.
And then, astonishingly, the same voice calls out "One Finnish soldier can beat an entire company of Russians!"
The General turns a dangerous shade of purple, and orders an entire reinforced company, 150 men, with light artillery and close air support, to do whatever is needed to kill this Finn, and bring his body back.
The company march off into the snow, and a huge battle can be heard. Planes streak overhead, bombs explode, machine guns and artillery fire shatter the air. And then, silence.
No! Not quite! A badly wounded Russian soldier, moaning from his injuries, is bravely crawling back towards the Russian lines. As he nears, this sole survivor cries out with his last breath, "General! It's a trap! Don't send any more men!" ...
"There are two of them!"
