The Hague, Netherlands is often referred as the Nagasaki of the Netherlands due to the fact that it was nuked by Soviet Forces during the Third World War in 1965. The Soviets had marched on Europe, conquering Germany, Italy, Greece and Austria and had their sights set on the low countries. However, Soviet forces were bogged down near the Rhine. While both the allies (US, UK, France, and the West German Exile Government) and Warsaw Pact had not yet used Nukes (though there were threats from nations like Cuba to nuke Miami, Atlanta and New Orleans, while the French had threatened to nuke Leipzig) no side used them until the Soviets nuked The Hague, where a number of allied forces were gathered.
The bomb, a Tsar Bomba weapon, completely destroyed The Hague and killed nearly half a million people during the blast, with cancer rates being quite high in the Benelux region for nearly a half century. While the bomb effectively crippled Soviet forces and put the majority of the continent under some sort of Soviet control, it also brought an end to the war with the treaty of London where newly socialist France, The Netherlands, Belgium, and Luxembourg, Denmark and Finland, along with conquered Italy and Greece, joined the Warsaw Pact. However, the treaty also forbade use of nuclear weapons, though the Soviets felt it was worth it until the fall of European continental communism in the late 2000's.
As for The Hague itself, the Soviets rebuilt it in the Brutalist style and its been frequently called "one of the ugliest cities in Europe." However, with a return to a democratic system, there has been more original architecture rebuilt in the city center.
