Question: What happened when the ruler of the country that retaliated for a surprise invasion during first world war was removed from power?

<P0-S0> in world war ii, it was recognised that the rhine would present a formidable natural obstacle to the invasion of germany, by the western allies. <P0-S1> the rhine bridge at arnhem, immortalized in the book, a bridge too far and the film, was a central focus of the battle for arnhem, during the failed operation market garden of september 1944. the bridges at nijmegen, over the waal distributary of the rhine, were also an objective of operation market garden. <P0-S2> in a separate operation, the ludendorff bridge, crossing the rhine at remagen, became famous, when u.s. forces were able to capture it intact – much to their own surprise – after the germans failed to demolish it. <P0-S3> this also became the subject of a film, the bridge at remagen. <P0-S4> seven days to the river rhine was a warsaw pact war plan for an invasion of western europe during the cold war. <SEP> <P1-S0> Afterwards, Makarov kills Allen, aware of his true identity, and leaves his body behind to spark a war between Russia and the United States. <P1-S1> Outraged by an apparent American-sponsored terrorist attack, Russia retaliates by launching a surprise invasion on the East Coast of the United States. <P1-S2> With no evidence of Makarov's involvement in the airport massacre, Task Force 141 is sent to Rio de Janeiro to capture his arms dealer, Alejandro Rojas. <P1-S3> They succeed and learn that Makarov's nemesis is being held in a Russian gulag. <P1-S4> They assault the gulag and rescue the prisoner: Captain Price, Soap's previous commanding officer in the SAS.Price agrees to help Task Force 141 but insists on ending the United States' war with Russia. <P1-S5> After raiding a Russian port, Price launches a ballistic missile towards Washington, D.C. and detonates it in the upper atmosphere. <P1-S6> Allen is soon sent on an undercover mission for the CIA, joining Vladimir Makarov in a mass shooting at an airport in Moscow, Russia. <P1-S7> The resulting EMP blast disables all electronic devices across the Eastern Seaboard, giving the Americans a much-needed advantage. <P1-S8> Soldiers fighting in D.C. narrowly avoid a bombing run of Russian-occupied strategic structures by the United States Air Force, lighting green flares atop the White House to show that the city remains in American hands. <SEP> <P2-S0> Following the abdication of Nicholas II of Russia, the Russian Provisional Government was established. <P2-S1> The Russian Revolution is the series of revolutions in Russia in 1917, which destroyed the Tsarist autocracy and led to the creation of the Soviet Union. <P2-S2> In October 1917, a red faction revolution occurred in which the Red Guard, armed groups of workers and deserting soldiers directed by the Bolshevik Party, seized control of Saint Petersburg (then known as Petrograd) and began an immediate armed takeover of cities and villages throughout the former Russian Empire. <SEP> <P3-S0> when world war ii broke out in 1939, bergmann sought to join the south african army, but as he felt his name was too german-sounding (there was significant anti-german feeling as the war loomed, and as the nazi persecution of the jews and the holocaust had not yet happened, this feeling made no distinction between germans and german jews), he removed the second "n" from his name, adopting the dutch variation of the surname. <SEP> <P4-S0> Nicholas II -- last Czar of Russia, titular King of Poland, and Grand Duke of Finland. <P4-S1> His rule ended with the Russian Revolution. <P4-S2> Nicholas was killed on 17 July 1918.
