We put criminals in jail. If the deeds in these nations are so horrible, we should put an end to the madness. Do you support such a war or are you "cool with it" as well?
If Germany had not tried to expand borders, merely was content with ethnic cleansing, should we have gone to war against the Nazis?
No on the answer to moral crusading and Nazi Germany - which is a classic Republican position. In fact the USA only went to war against Germany because Germany declared war on us. Lastly, the fog of all out war allowed the Nazis to carry out the holocaust. WW2 can be said to have been a strategic failure - in that it was started to save Poland from German invasion.
