Sure they used religion, but that does not mean they were not also religious. Most powerful religious leaders today use religion, but if you're arguing that this means they are not religious you are a very lonely (and incorrect) voice. One does not exclude the other. And in Hitler's case they very clearly go hand in hand.
âoeMy feelings as a Christian points me to my Lord and Savior as a fighter. It points me to the man who once in loneliness, surrounded by a few followers, recognized these Jews for what they were and summoned men to fight against them and who, Godâ(TM)s truth! was greatest not as a sufferer but as a fighter. In boundless love as a Christian and as a man I read through the passage which tells us how the Lord at last rose in His might and seized the scourge to drive out of the Temple the brood of vipers and adders. How terrific was his fight against the Jewish poison. Today, after two thousand years, with deepest emotion I recognize more profoundly than ever before the fact that it was for this that He had to shed his blood upon the Cross. As a Christian I have no duty to allow myself to be cheated, but I have the duty to be a fighter for truth and justiceâ¦ And if there is anything which could demonstrate that we are acting rightly, it is the distress that daily grows. For as a Christian I have also a duty to my own people. And when I look on my people I see them work and work and toil and labor, and at the end of the week they have only for their wages wretchedness and misery. When I go out in the morning and see these men standing in their queues and look into their pinched faces, then I believe I would be no Christian, but a very devil, if I felt no pity for them, if I did not, as did our Lord two thousand years ago, turn against those by whom today this poor people are plundered and exposed.â

As to Saddam, you seem to be arguing from a context where people are brought up secularly and then presented with religion as a tool. That may be your life experience, but that's not how people grow up in religious nations.
