The most important fact is the anglos wanted the Tzar Nick2 to keep fighting on their side in WW1 regardless how horrendous the casualties and damage done to Russia. Rasputin wanted peace but failed to persuade Nick2 and was hated by the anglo warring party. His murder was facilitated by the limey secret service. He was shot by the anglo secret agent Oswald Rayner and the russian homo prince Yusupov(who hosted Rasputin's Last Supper and was educated b4 WW1 in england.) Yusupov died peacefully in Paree at the ripe old age of 80 in 1967, 50 yrs after the russian commie revolution.
