It become a concern of the military planners due to the high casualty the marines suffered during the taking of Iwo Jima. Also the battle proved that even though the battle was an American Victory the Japanese army is prepared to die defending and willing to wage a suicide attacks even though they already know that they lost the war. That also attacking the Japanese Home Islands would be a costly attack of lives of american soldiers and the new strategy develop in Iwo Jima would be an arduous battle if the Americans would invade the Japanese Island with the Japanese people that is already to prepare to die fighting.
Peter the Great was a czar in Russia that did some extensive reforms in an attempt to make Russia great. He started a lot of wars but it was to expand his Tsardom and it worked. It became a major European power. He also led a cultural revolution that replaced the more traditional and medieval social and political systems into a modern one with modern science and based on the enlightenment. He founded and developed the city of St. Petersburg which was the capital of Russia until 1917.
Peter reorganized the Russian army and dreamed of making Russia a maritime power. He faced a lot of opposition to these policies at home and he brutally suppressed rebellions against his authority, including by the Streltsy, Bashkirs, Astrakhan, and the greatest civil uprising of his reign, the Bulavin Rebellion.
