Considering the Soviet experience in WWII (and Israel currently the world's #1 terrorist state), hardly seems surprising:

The Numbers: The populations of the United States and the USSR were about the same, 130,000,000, when both nations went to war within six months of each other in 1941. To Americans, we were sending our boys to fight a foreign war that we'd never experience. To the Soviets, it was an up front and personal war of monumental savagery. America would lose slightly more than 400,000 soldiers (killed or missing) and almost no civilians during World War II and the USSR, depending on which historian you believe, would lose at least 11,000,000 soldiers (killed and missing) as well as somewhere between 7,000,000 and 20,000,000 million of its civilian population during the Great Patriotic War.
Looking only at Anglo-American forces engaged against German soldiers on our two fronts, northwest Europe and Italy, the United States lost 139,380 soldiers (killed and missing) during the conflict. General Eisenhower had just over 3,000,000 men under his command, with about a third of them safely in England, and faced a German Army of less than 1,500,000 of which our forces killed 834,314. At the same time, Soviet armies in excess of 20,000,000 soldiers were fighting German armies totaling 5,700,000 at their strongest and killed 2,415,690 of them as they fought their way out of Russia and on to Berlin.
These are the numbers that make Russians bristle when they hear Americans say to each other that we won the war in Europe. For every American soldier killed fighting Germans, eighty Soviet soldiers died fighting them. On the other hand, Americans deeply resent Soviet textbooks telling their children their version of history with passages such as:
"In June, 1944, when it had become obvious that the Soviet Union was capable of defeating Hitler's Germany with her forces alone, England and the USA opened the second front.
"On 6 June, 1944, the Allied forces, commanded by General Eisenhower, landed in Normandy (Northern France). The Anglo-American forces met with practically no opposition from the Hitlerites, and advanced into the heart of France"ii
Studied without bias born of the Cold War, one can understand the Soviet description of the facts. Some historians of World War II suggest that by mid 1944 the USSR was strong enough to defeat Germany eventually, without any Anglo-American second front. With respect to the "practically no opposition" propaganda phrase it is also true that the Soviets, who routinely faced battles involving several hundred thousand soldiers on both sides, did not regard the 67,000 Germans defending Normandy on June 6th as serious opposition.iii To the Soviets, fighting 390,000 Germans in the area of a single city (Stalingrad) was meeting serious opposition
