I found an extended criticism uttered by the religious leader Osho against Christianity and would like to confirm here if several statements made in it are true. I have removed most of the quote for brevity:

Question 1
OSHO,ARE YOU ESPECIALLY AGAINST CHRISTIANITY?
...(t)he worst kind of indoctrination that Christianity has put into people's minds (is) (1) (t)he idea of the crusade, of a religious war, (which is a) great contribution of Christianity. Mohammedanism learned it from Christianity; they cannot claim to be the originators of the idea. They call it jehad, holy war, but they came five hundred years later than Jesus. Christianity had already created in people's minds the idea that a war too can be religious.
(2) ...the first world war happened in the Christian context, the second world war happened in the Christian context, and the third world war is going to happen in the Christian context.
(3) Adolf Hitler was saying to his people, "This war is holy"; it was a crusade. He was simply using Christianity's contribution. (4) He was a Christian, and he believed himself to be the reincarnation of the prophet, Elijah.(5) Adolf Hitler was blessed by the German archbishop, who told him, "You are going to win because Christ is with you and God is with you." (6) And the same fools were blessing Winston Churchill, saying, "God is with you and Christ is with you -- you are sure to win."
(7) Mussolini was being blessed by the pope -- a representative, an infallible representative, of Jesus Christ.
To paraphrase them, how true is each of the following:
If they are not true, where might he have gotten the ideas from?
Thanks.
That "religious war" is a concept that originated from Christianity;
Given that religious war appears in the Rig Veda as a Good Thing, the concept of religious war predates Christianity. For example,
Discriminate between the Aryas and those wlio are Dasyus, restraining those who perform no religious rites, compel them to submit to the performer of sacrifices: be thou, who art powerful, the encourager of the sacrificer.
which can be paraphrased as "Indra, help us who sacrifice to you in our holy war against the unbelievers." The quote is from pp 137-138 in this translation: https://archive.org/details/rigvedasanhita01wils/page/138/mode/2up
For more on warfare in ancient Hinduism, see Hume, R. (1916), "Hinduism and War", The American Journal of Theology 20(1), 31-44: http://www.jstor.org/stable/3155809 (old, but conveniently online and the main point is sound).
For a modern (and Indian) take on it, see D.N. Jha, Against The Grain: Notes on Identity, Intolerance and History, Texas A&M University Press, 2018.
That World War I and II happened because of Christianity;
History shows us that neighbouring states will often wage war against each other, whether they are of the same or different religions. This is even the case where the religions prohibit violence and war. There seems no reason to think this is true (especially if we date the start of WWII to 1937, with the opening of the 2nd Sino-Japanese War).
That Hitler called his war holy [and the similar later claims]
Religion is widely used for propaganda, with chaplains leading soldiers in prayer for victory, the state church supporting the war effort. Even if the war is purely about power and greed, with no religious component, religious differences are sometimes used to portray the war as "holy" (Tamurlane was very active in this regard).
It's a very old tradition, not restricted to Christianity, and not invented by Christianity. Courtesy of the oldest Hindu scriptures being our oldest known religious writings, and this kind of thing appearing in them, we could speculatively attribute the invention of this kind of thing to Hinduism, but but it is surely much older, with origins lost in prehistory.
If they are not true, where might he have gotten the ideas from?
I can't tell from the transcript. In the following discussion, the are multiple factual errors given in support of these claims:
They have been fighting -- Japan and China have been fighting and both are Buddhist -- but neither Japanese Buddhist priests nor Chinese Buddhist priests were in any way involved, not even by giving a blessing.
All atomic weapons, nuclear weapons, are produced in the Christian context.
to give just two examples. These kinds of "facts" are readily seen to be false given the desire to check them (e.g., noting the actions of Buddhist priests in the 2nd Sino-Japanese War (and earlier in the Imjin War), noting that China and India had atomic weapons before 1985). If "facts" like these, "learned" from wherever, are the origin of the expressed beliefs, then IMO insufficient fact-checking has been done. It is possible that this is the case, given other grossly incorrect statements in the transcript - the anti-Christianity could result from swallowing a poisonous amount of non-fact as "fact". OTOH, it could simply be a bunch of virulent propaganda for anti-Christianity. Instead of ideas gotten from somewhere, they could be ideas invented purely as propaganda.
(India's 1974 atomic bomb test was codenamed Smiling Buddha. The test was, of course, for "peaceful purposes".)
