How far was Lenin responsible for the Bolsheviks growing hold on power after the October revolutions?

Lenin led the revolution. When he returned from Switzerland, he inspired the masses to revolt against the Burgeoise. Also, he inspired soldiers to convert to the cause. Thus, he was a major influence in the revolution. Partly right. In fact Russia had threee revolutions to deal with. 1905 - after a enormous defeat against Japan (the entire navy was lost) the Tsar had to deal with the Bolsjewist and Mensjewist party who took over control over several cities. The revolution was surpressed, and Nikolai II promised to reform the country. This didn't happen though and in February 1917, nikolai II was abducted and a temporary government was formed. Main people in this government were anton Kerenski (a former journalist if I'm not mistaken) and Prince Llov (a liberal) Allthough thy tried to reform the country, they didn't succeed to prevent the bolsjewiki to overthrow this government in november 1917 (done by Lenin, trotski and Stalin). Lenin took control over the government. A bit later, the civil war started which lasted for three years (1917 - 1920) eventually won by Lenin and his frieds (the jew Trotsky was the main architect to victory here). Since then, Propaganda stated only one heroic revolution took place in 1917. The truth is, that Lenin just entered the room and said something like. Gentlemen, we take over control. It seems as if WWI had just as much responsibility for the Oct. Revolution as the Bolsheviks did. The autocracy surely would've retained power without entrence into the war. The situation in Russia by 1917 had become very unsatisfactory and Lenins return to the coutry with the help of the Germans was vital. This is not because of Lenins major influence on the revolution but his presence in a moment of possible change to the government, the war played a big part but it was Lenin who utalised the situation to his advantage and he knew when the time had come for a possible Bolshevik take over.
