One thought leads to another. Let's suppose that a well-funded group of fanatics secure enough fissionable material to make a small fission bomb. Or hey, let's go for a small thermonuclear device, say on the order of 400-500k ton.
Now, let's assume they ignite in the country of their choice, perhaps
1. in front of the US whitehouse.
2. near the Eiffel tower
3. near windsor castle
4. the Kremlin
5. near Nielsen's hairdress
6. where ever, you get the idea.
Now, let's assume we have tracked the responsible group down to the mountains of Afghanistan near the Pakistan border.
In response, what would the
1. US
2. French
3. Great Britain
4. Russia
5. Norway
do?
Would the immediate reaction be the use of tactical nukes?
