How is Iran "the world leader of state-sponsored terrorism"? When was the last time Iran conducted a terrorist attack on us?
Iran is the world leader in fighting ISIS. If it wasn't for them Islamic State would be ruling in Baghdad and Damascus right now.

I'll bet you think the Russians killed more Nazis during WWII, too!
They did. They were so good at it, Ike let them take Berlin to give the Army a rest - the Soviets revenge shelled the city and people into dust then followed up with infantry attacks all the way to the Reichstag.
Considering the sheer number of German casualties on the Eastern Front compared to other locales, it seems certain that the Soviets killed far more Germans than any other Allied country. (Yes, I know not all Germans were Nazis, but this is probably as close an approximation as we can get.)
Wikipedia , citing
Deutsche militärische Verluste im Zweiten Weltkrieg by Rüdiger Overmans, gives 5.3 million total killed, of which 2.7M were on the Eastern Front through the end of 1944, 340K on the Western Front through the same period, and 1.2M during the final battles in Germany (1945), with lesser amounts in other locales (Italy, Poland, Scandinavia, etc.)
