UK (where I live atm): Dragon attacks. Dragon finds Underground network and makes a nest in London, being easily provided by food from southern fairy Londoners taking the tube train to work, refusing to admit that the dragon is a danger and expressing disbelief in the actual existence of the dragon. London becomes complete no go zone due to endless traffic jams caused by all the southerners flocking to the 2 marches, the first protesting lack of government action against dragons, the second protesting the suggested cull on dragons. A third group arrives, protesting for the banning of Dragon Hunting.
The police finally locate the dragon, track it into the Underground, and shoot and kill a Brazilian electrician and 2 black kids.
Wales writes to England and offers support, since they have been dealing with dragons for thousands of years. Government finds solution by consensus: Remove catalytic converters from cars and remove filters from factory chimneys, massively increasing pollution: Air is now so thick with particles it is ruled unsafe for air travel, dragon is not allowed to fly, problem solved.
Northern England and Scotland barely take any notice: anything bad that happens to London is more than deserved and also they are safe in the knowledge that if the dragon started shit North of the Watford Gap, locals would come forward and beat the living shit out of it with the first thing that comes to hand.
In Spain (where Im from): Government would complain it is hampered in its ability to deal with dragon related crisis because of nonpayment of taxes by the workforce: workforce then goes on massive national strike to protest the proposed dragon tax. Entire army is overseas, on peacekeeping duty with the UN. National hysteria rises as dragon burns the north, moves south and destroys the central plain, decimating population of Madrid and cutting off the government from outside communication. Everyone comments how dragons never were dangerous when Franco was in power. Eventually dragon moves south into Andalusia: first old Andalusian peasant's wife it encounters hit it with her stick so hard it FUCKING DROPS DEAD, while she yells "Chaaaaaape, Bicho!", she then lifts it on her own, calls the goats in, butchers the dragon and makes sausages.
