Remember the French? If it was not for them there very likely would be no United States of America. Remember over 50 years of at least European peace? Notice that a single individual, Vladimir Putin has thrown that peace out the window for what he apparently sees as his own self-aggrandizement. Where do you draw the line for such? I think it is very clear that the NATO allies and others are going to have to sooner or later kick the Russians out of Ukraine (and possibly other places they don't belong). Appeasement of dictators (even when "elected" in a "managed Democracy") has never ever worked to the advantage of the people of the world; things always get worse until right is reasserted by might of the exasperated many. There is always a huge cost which the dictators just laugh at, it's not them getting hurt. One of the biggest costs is always to the people of the Dictator's own country.
Germany and Japan, as examples, did not stop until they got their butts thoroughly kicked in the mid-1940s and at some point, if diplomatic overtures don't get that educating done to Putin, some level of butt kicking will be essential. Unfortunately, it won't actually be Putin's butt that gets kicked, it will be many of his countrymen who pay the price. Germany and Japan (and their leaders) have learned from their mistakes but not all wannabe emperors have (or necessarily will). See Hamilton's "love of power" paragraph again.
It should also be clear, from the "God," "Religion," "Bible…," etc., sections above that any war based on "religion" distinctions among people is wholly invalid, it's just a people vs. people power grab (or at least of those claiming "leadership"). You may have noticed that Putin went from being an atheist 20 some years ago to a Russian Orthodox Christian as one more (probably) lie to add to his "liberate" and "Nazi" and "Ukraine is Russia" lies to justify to his countrymen why they should willingly die to aggrandize Putin. The invalid support for the (human created) religious views held by (some) Jews and (some) Hamas/Palestinians, etc., is just as surely not legitimate reason for wars in the so-called Middle East or Africa. In fact, the only justified war is one to defeat an aggressor nation that starts a power grab by might.
